Wandering through the realms of the cosmos, pondering its huge vastness

Transits and Occultations

#ThrowbackThursday post: June 6, 2012 Transit of Venus

transit of venus copy copy

 

June 6th last year, stargazers from across the globe gathered together to watch one of the rarest astronomical spectacles.

Many turned their attention to the daytime sky to view the planet Venus passing directly between the Sun and Earth – a transit that won’t occur again for another 105 years.

The transit of Venus happens in pairs eight years apart – but then with more than a century between cycles. During the pass, Venus appeared as a small, dark round spot moving across the face of the sun.

Moon and Jupiter – January 22, 2013

Last January 22, 2013, the waxing gibbous moon appeared near the bright planet Jupiter in the evening sky.

As seen from the Philippines, the Moon and  Jupiter made a close approach within roughly 5 degrees of each other. Some folks in the Southern Hemisphere, however have seen Jupiter completely disappear behind the moon – an occultation.

During this event, the Moon was at mag -12.3, and Jupiter at mag -2.6, both in the constellation Taurus.

The sky condition was mostly cloudy. When the clouds parted, I was able to a couple of wide angle images which includes the two famous star clusters in Taurus — the Hyades and the Pleiades. In another image, the moon was shot at two different exposures to show the amount of separation between it and Jupiter.

Images were taken from Bulacan, Philippines around 8:40 – 9:00 pm PHT.

Lunar Occultation of Jupiter – August 12, 2012

During the early morning hours of August 12, Philippine sky observers had a great chance of witnessing a relatively rare occultation of Jupiter (and some of its largest satellites) by our Moon. In astronomy, an occultation is an event that occurs when an apparently larger body passes in front of an apparently smaller one. In this case, the moon passed in front of the planet Jupiter; the pair being visible in the morning sky in the Philippines about 5 hours and 53 minutes before the Sun. At the moment of closest approach, the Moon was at mag -11.3, and Jupiter at mag -2.2, both in the constellation Taurus.

Despite the presence of hazy skies and thin clouds, we were lucky to have been able to observed the occultation event. Once I located the moon with my naked eye, I immediately pointed my superzoom camera  to it and took an image. I found Jupiter close to the moon but it was covered with haze. A few minutes later, Jupiter slipped behind the bright lunar limb and was visible no longer. Half an hour later, I tried to capture a video of the reappearance of  Jupiter, but the clouds had thickened to the point where I could no longer find the moon. When the clouds  had finally gone out of sight, Jupiter was already emerging from behind the dark limb.

Still, considering the less-than-ideal conditions, it was quite a successful observation. 🙂

Sky condition: 70-80% cloudy

Skywatching Highlights: August 2012

This month, weather conditions permitting, skywatchers will be treated to the Perseid meteor shower, several planet conjunctions, a “blue moon” and a relatively rare lunar occultation of Jupiter (visible for some parts of the globe).

August 7-14: Spica, Saturn and Mars at Dusk 

The planets Saturn and Mars and the star Spica are close together in the first half of the month, low above the western horizon at dusk. They will form a triangle on the 7th an hour after sunset. Saturn will be the top of the triangle, while Mars will be on the lower right corner. Each side of the triangle is about 5 degrees. On the 14th, they will form an almost straight line: Saturn topmost with Mars lying between Saturn and Spica.

August 12: Occultation of Jupiter by the Moon

For Philippine observers,  the waning crescent Moon will pass in front of Jupiter and its moons during a relatively rare event called occultation on the morning of August 12. In astronomy, an occultation occurs when one object is hidden by another larger object that passes between it and the observer. Prospects and timings for the event vary with location.

The event takes place while Jupiter and the Moon are low in the sky during the wee hours of the morning.

Local circumstances:

2012 Aug 12 02:43 Occultation disappearance of Jupiter (Mag -2.2)
2012 Aug 12 03:16 Occultation reappearance of Io (Mag 5.5)
2012 Aug 12 03:17 Occultation reappearance of Jupiter (Mag -2.2)
2012 Aug 12 03:18 Occultation reappearance of Europa (Mag 5.7)
2012 Aug 12 03:20 Occultation reappearance of Callisto (Mag 6.1)
2012 Aug 12 03:32 Occultation reappearance of Ganymede (Mag 5.0)

August 11, 12: Perseid Meteor Shower

The Perseids is one of the best annual meteor showers.

The best time to watch for Perseids is between midnight and dawn. This is when the shower’s radiant located between the constellations Cassiopeia and Perseus, lies highest in the northeast sky.

By the 12th, the moon will only be 25% illuminated and not nearly as intense as when near its full phase. This will allow fainter meteors to be seen as long as the moon lies outside your field of view.

Tip: Find a safe dark location with clear skies in the early morning hours in order to see the shower. This year, the shower peaks on a weekend so it’s more convenient to stay up late.

August 14: A line of planets along with a thin, waning, crescent Moon before dawn

Before dawn on the morning of the 14th August the planets Mercury, Venus and Jupiter and the Moon will line up in the eastern sky.  Look for A very thin crescent Moon to the upper right of Mercury an hour before sunrise in the northeast. Venus is to the upper right of the Moon, and a few degrees above them is Jupiter.

August 22: Waxing Crescent Moon joins Saturn, Mars and Spica

On the evening of the 22nd, a waxing crescent Moon, Mars, and Saturn will all lie within a circle just 6° in diameter.

August 31: Blue Moon (second full moon of August)

On the 31st, we will be able to witness a Blue Moon, the term given to the second full Moon in a calendar month.  But don’t expect it to be blue — the term has nothing to do with the color of the moon. [Origin of the term blue moon]

Clear skies!

 


Crescent Moon, Venus and Jupiter at Predawn on July 15th

Eastern sky at 4:00 am local time. Manila, Philippines. Image: Stellarium

Philippine sky observers will have a great chance to see all of the three  brightest objects of the night sky in close proximity to each other this weekend (weather permitting). On the morning of July 15th, the waning crescent moon will join the very bright “stars” Jupiter (upper) and Venus (lower) to form a nice celestial grouping, along with two prominent open star clusters — the Pleiades and the V-shaped Hyades —  in the constellation Taurus.

Venus has reached its greatest illuminated extent in Earth’s sky last July 12. Thus, it appears so dazzling now as a “morning star”  in our predawn sky, near Jupiter.

Meanwhile, in other parts of the globe, this celestial grouping event will be viewed as an occultation of Jupiter by the moon. An occultation is an event in which a celestial body covers another, farther away object, such as when the moon covers a star or a planet or when a planet or an asteroid covers a far away star. For this event, the moon will cover Jupiter for about an hour (the exact time and durtaion of the occultation is  dependent on the observer’s location). View the visibility map and timings of this event from IOTA.

Seeing Jupiter’s occultation is possible with the naked eye, but the look through a telescope, even using a small magnification, is marvelous. At first, two of Jupiter’s large moons (Io and Europa) will disappear behind the moon, then Jupiter will disappear and then the other two moons (Ganymede and Callisto).

Places close to the southeast will witness a ‘grazing occulation’ when Jupiter and its moons will skim the edge of the Moon. This will be well worth seeing through a telescope and Jupiter’s moons may be seen blinking in and out of view as they pass behind the lunar mountains. Further north and west a very close conjunction will be seen.

Don’t worry because even though we won’t be seeing this event in the Philippines this weekend, we are still lucky enough to see a very rare version of such an event next month, during the morning of August 12, 2012. That will be surely worth getting up to see!

Observing occultations can also contribute to science. During the 80’s, Uranus occulated a distant star. Photos of the events showed that just before and after the occultation the star blinked several times. The theory then was developed that Uranus has a set of rings (like Saturn). When Voyager 2 reached Uranus it detected and photographed the predicted rings.

Don’t miss this event. Clear skies!

Venus Transit Observation in the Philippines

Viewing the Sun’s mole: People across the globe witnessed a very rare spectacular event that won’t be repeated until 2117.

I observed the whole duration of the  final  Transit of Venus of our lifetime at the College of Science Amphitheater in UP Diliman in a public viewing event  called ‘Rekindling Venus’ organized by members of various school-based astronomy organizations in the Philippines a last June 6, 2012.

There were lectures, talks, astro-images exhibit, free planetarium shows and telescope viewing, and more during the event, which have been attended by a lot of astronomy-enthusiasts coming from different places.

The sky was about 40-50% cloudy that day but it didn’t rain despite the weather forecast.

Observers set up their telescopes and pointed at the sun to view the transit.

Me and my own simple set up featuring my trusty Galileoscope equipped with a Baader 5.0 ND solar filter.

A lecture by Dr. Perry Esguerra of the National Institute of Physics explaining the phenomenon.

All smiles: Members of the UP Astrosoc, UPLB Astrosoc, and RTU Astrosoc posed for a group photo after the event . Image credit: Norman Marigza

Local newsgroups were present during the event and I was unfortunately spotted for a short interview. Haha!

This event was surely a memorable one.

Kudos to all the organizers and thank you to everyone who joined us in this event!


Art and Astronomy: Transit of Venus by Norman Marigza

Transit of Venus (medium: acrylic)

Only a few days left to the last transit of Venus of our lifetimes! Miss it and you won’t be able to witness it until the year 2117.

Amateur and professional astronomers from all over the globe were already gearing up for this big event. There were talks, lectures, public observations, videos, and other several projects and activities initiated by various local groups to promote this event among the public.

But one of  our astro-friends here has another cool way of sharing his knowledge and enthusiasm for this upcoming event, and that is through painting.

Shown above is an artistic depiction of the upcoming Transit of Venus created by Norman Marigza, a young Filipino artist who is also in the field of Physics and Astronomy. According to him, his two greatest passions in life are Art and Astronomy, hence he can do both. He’s surely a gifted person, isn’t he?

To see his other astro-artworks, please visit his website http://blogstargazers.blogspot.com/2010/01/astroart-by-norman.html

During the transit of Venus, we will be able to see the Venus as a small dot gliding slowly across the face of the sun. It happens when Venus passes directly between Earth and the Sun.

Historically, this rare alignment is how we measured the size of our solar system.


Rekindling Venus: Experience A Rare Celestial Event

Next month we will be the last people living today to witness one of the rarest astronomical events. On June 6, a special celestial event called the transit of Venus will take place, and it won’t be repeated in your lifetime.

During the transit, Venus will pass directly in front of the sun from Earth’s perspective, appearing as a small moving black dot.

The entire transit can be witnessed from eastern Asia, eastern Australia, New Zealand and the western Pacific, as well as Alaska, northern Canada and almost all of Greenland.

How rare is this astronomical event?

Transits of Venus occur in a pattern that repeats every 243 years with pairs of transits eight years apart separated by gaps of 121½ years and 105½ years. Only six of these transit have been recorded by civilization: 1639, 1761, 1769, 1874, 1882, and 2004. This June’s transit, the end of the 2004-2012 pair, won’t be repeated until the December 2117. This is the last chance for anyone alive today to see the rare celestial sight. Fortunately, the event is widely visible.

Unlike a total eclipse of the sun, which is visible only within a long narrow track traced by the moon’s shadow, during the 2012 transit of Venus the entire hemisphere of Earth facing the sun will get to see at least part of the planet’s solar crossing.

Importance

Astronomers during the 18th Century travelled thousands of miles and risked their lives to witness this precious sight.

They did so because they believed Venus held the key to the most pressing astronomical quest of the age: the size of the solar system.

In 1716, astronomer Edmund Halley realized that by timing the transits of 1761 and 1769 from widely-spaced locations on Earth it should be possible to triangulate the distance to Venus using the principles of parallax and give the distance between Earth and the Sun.

For astronomers today, the Transit of Venus offers a chance to gain insights into the planet’s notoriously thick, cloudy atmosphere, and use the refraction of sunlight to finetune techniques for hunting planets orbiting distant stars.

One of the most useful exercises will be to compare observations of the transit made by Earth-based telescopes, orbital telescopes and robot probes.

The Transit of Venus (TOV) is among the rarest astronomical phenomena and won’t happen again until the year 2117. So prepare now, and don’t miss out on this extremely special event!

Observing the TOV from the Philippines

Filipinos are lucky because the entire Philippines is well positioned to witness the transit of Venus on Wednesday 6th June 2012.

To those who are planning to observe this rare event, you might just be interested in joining us in this free public viewing.

Safe Viewing

Warning: NEVER look at the sun with your naked eye, binoculars or a telescope. Serious and permanent eye damage, including blindness, can result.

The Black Drop Effect

The black drop effect occurs when Venus appears to “connect” to the edge of the Sun before actually reaching the edge. You can model the black drop effect by slowly pinching your index finger and thumb together. Your fingers seem to meet even before they touch. This optical phenomenon was originally thought to provide proof of Venus having an atmosphere. For an explanation of the black drop effect, check out the following links:

Transit of Venus Map in Many Languages

On 6 June, an event that takes place only four times every two centuries will enthral the world’s astronomers, as it has ever since the 1600s – but now it can provide priceless data in the hunt for habitable planets in deep space and in re-measuring the distance of the sun from Earth.

Venus will appear as a tiny speck on one side of the Sun in a few weeks and will slowly traverse the solar disc for a few hours. The movement of that little black dot may seem insignificant. But it is one of the rarest sights in astronomy, an event known as a transit of Venus. Miss this one and you will have to wait until 2117 for the next.

Image credit: NASA/LMSAL

As seen from Earth, only transits of Mercury and Venus are possible. On average, there are 13 transits of Mercury each century. In contrast, transits of Venus occur in pairs with more than a century separating each pair.

For Northern Hemisphere locations above latitude ~67° north (including the Philippines) all of the transit is visible regardless of the longitude.

A lot of astronomy-enthusiasts globally are preparing for this rare event. Some are even planning to travel in places where the transit will be fully visible.

As part of this preparation, visibility maps of the transit were created by volunteer groups to guide local observers. One of the efforts is called the Transit of Venus Project which is part of the Astronomers Without Borders (AWB) program. AWB is a global collaboration in astronomy.

Aside from providing useful information to the public about this event, the TOV Project also aims to form a collection of translated maps of the 2012 transit of Venus for different languages so that the transit of Venus will be enjoyed by more people around the world. Of course,  some people would appreciate a map in their own native language.

Michael Zeiler of  Eclipse-maps.com (and also one of the curators of the TOV Project website) sent me a message via Twitter asking for help with translating a summary map of the transit of Venus (June 5-6, 2012) into Filipino.

Here is a copy of the map:

These are the phrases to translate: World visibility of the transit of Venus on June 5 & 6, 2012 Venus overhead at transit maximum Entire transit visible Transit not visible Transit starts before sunset and ends after following sunrise Transit starts before sunrise and ends after sunset Transit visible from sunrise until end Transit visible from start until sunset Venus touches Sun’s disk at sunrise Venus within Sun’s disk at sunrise Venus within Sun’s disk at sunset Venus touches Sun’s disk at sunset

I made a draft of the translation in Filipino and consulted some professors from the Filipino Department of UP Diliman. Upon deciding that it the translated words were good enough, I emailed everything to Mr. Zeiler and he produced this map containing the translated phrases.

Don’t miss this rare spectacle! 🙂 Clear skies!


Notable Celestial Events in 2012

This year comes with its share of many remarkable skywatching events that we can participate in.  The most important is the rare transit of Venus across the face of the Sun in  June 2012. The next time this will occur again is in 2117. We have the unique opportunity to observe this. (A note to Philippine observers: We are in a good location for this event!)  Moreover, there’s also the Mercury elongation in February, Jupiter-Venus conjunction on March 13-15, the solar eclipses on May 21 and November 14 and  our favorite annual meteor showers.

The list below also contains some tips for Philippine observers.

Clear skies and happy observing! 🙂

February 20 – March 12 :  Best Chance to see Mercury

The planet Mercury will be far enough from the Sun’s glare to be visible shortly after sunset. Mercury will reach greatest elongation from the Sun on March 5, reaching a relatively bright magnitude of about -1. This will be your best chance to see the planet this year.

February 26 : Moon, Jupiter and Venus at Dusk

Look westward after sunset to see the moon and the dazzling planets Jupiter and Venus lighting up the western sky.

Moon, Venus and Jupiter | 6 pm | Manila

March 3 : Mars at Opposition

The red planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph this planet. Mars will be an imposing naked-eye sight, shining at magnitude -1.2, just a bit dimmer than Sirius, the brightest star, and will be visible in the sky all night long.

March 14 : Conjunction of Venus and Jupiter

The two brightest planets in the sky will be within 3 degrees of each other in the evening sky. On March 25 and 25, the crescent Moon will be near the two planets, creating a dazzling evening spectacle.

March 26 : Crescent Moon, Jupiter and Venus line up at Dusk

Watch for the young waxing crescent moon and the planets Jupiter and Venus near each other in the west after sunset. The moon, Venus and Jupiter rank as the brightest, second- and third-brightest heavenly bodies of nighttime respectively. This will be last chance in 2012 that you will see them all-together at dusk.

moon, venus, jupiter - march 2012

March 27: Venus at Greatest Eastern Elongation

Venus reaches its greatest eastern elongation and will be separated from the Sun by 46°, its greatest apparent distance from the sun on our sky’s dome. Venus will set about three hours after sunset during this event. At this superb evening elongation for the Northern Hemisphere, Venus will stand above the setting sun. This is a good time to look out for the Schroter Effect, which predicts that dichotomy the 50% lit phase occurs a few days early for evening elongation.

April 3: Venus near the Pleiades

Venus will appear to the left of the Pleiades star cluster.  Especially with binoculars or a small telescope, this bright plant should appear swimming in a sea of stars.

April 15 : Saturn at Opposition

The ringed planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph Saturn and its moons.

April 21, 22 : Lyrid Meteor Shower

The Lyrids are an average shower, usually producing about 20 meteors per hour at their peak. These meteors can produce bright dust trails that last for several seconds. The shower usually peaks on April 21 & 22, although some meteors can be visible from April 16 – 25. With no moon to get in the way this year, this really should be a good show. Look for meteors radiating from the constellation of Lyra after midnight.

*April 2012 is Global Astronomy Month!

May 21 : [Annular] Solar Eclipse

The path of annularity will begin in southern China and move east through Japan, the northern Pacific Ocean, and into the western United States. A partial eclipse will be visible throughout parts of eastern Asia and most of North America. (NASA Map and Eclipse Information) (Note: In the Philippines, we will be able to see a crescent sun at dawn.)

Partial Solar Eclipse | 6am | Manila

June 4 : Partial Lunar Eclipse

The eclipse will be visible throughout most of Asia, including the Philippines  Australia, the Pacific Ocean, and the Americas. (NASA Map and Eclipse Information) In the Philippines, we can observe this event as an eclipse at dusk, meaning we will be able to see an eclipsed moon rising.

eclipse magnitude:  37.6%
moonrise: 6:17 pm PHT
greatest eclipse: 7:03 pm PHT
partial eclipse ends: 8:07 pm PHT
penumbral eclipse ends: 9:19 pm PHT

June 6 : Transit of Venus Across the Sun

This extremely rare event will be entirely visible throughout most of eastern Asia, eastern Australia, and Alaska. A partial transit can be seen in progress at sunrise throughout Europe, western Asia, and eastern Africa. A partial transit can be seen in progress at sunset throughout most of North America, Central America, and western South America. The next transit will not take place until the year 2117.

August 12, 2012: Occultation of Jupiter by the Moon

For Philippine observers, the morning of 12 August sees the waning crescent Moon pass in front of Jupiter and its moons in a so-called occultation. Occultations are comparatively rare events, which offer good photo opportunities for amateur astronomers. Prospects and timings for the event vary with location.

The event takes place while Jupiter and the Moon are low in the sky during the wee hours of the morning.

Local circumstances:

2012 Aug 12 02:43 Occultation disappearance of Jupiter (Mag -2.2)
2012 Aug 12 03:16 Occultation reappearance of Io (Mag 5.5)
2012 Aug 12 03:17 Occultation reappearance of Jupiter (Mag -2.2)
2012 Aug 12 03:18 Occultation reappearance of Europa (Mag 5.7)
2012 Aug 12 03:20 Occultation reappearance of Callisto (Mag 6.1)
2012 Aug 12 03:32 Occultation reappearance of Ganymede (Mag 5.0)

August 11, 12 : Perseids Meteor Shower

The Perseids is one of the best meteor showers to observe, producing up to 60 meteors per hour at their peak. The shower’s peak usually occurs on August 11 & 12, but you may be able to see some meteors any time from July 23 – August 24. The radiant point for this shower will be in the constellation Perseus. The near last quarter moon will be hanging around for the show, but shouldn’t be too much of a problem for a shower with up to 60 meteors per hour. Find a location far from city lights and look to the northeast after midnight.

October 5 : Moon-Jupiter Conjunction

The King of the Planets and the crescent moon will reunite for a close celestial pairing. Check the eastern sky around midnight to spot these two objects that are less than one degree apart!

Moon and Jupiter at 11 pm | Manila

October 21, 22: Orionid Meteor Shower

The Orionid Meteor Shower usually reaches its peak around October 21, having an average of 20 meteors per hour. The Orionids are fast meteors and also have fireballs. These meteors radiate near the boundaries between the Great Hunter Orion and Gemini. The cometary debris left behind by Comet Halley — bits of ice, dust and rubble — create the Orionid meteor shower. It last visited Earth in 1986.

A good show could be experienced on any morning from October 20 – 24, but some meteors may be seen any time from October 17 – 25. The first quarter moon will set by midnight, leaving a dark sky for what should be a good show.

The best time to view these meteors is usually in the wee hours before dawn. That time holds true no matter what time zone you’re in.

The red lines illustrate the position of the radiant for the Orionid Meteor Shower. The radiant is the point in the sky from which the meteors appear to originate from.

November 13 : Total Solar Eclipse

The path of totality will only be visible in parts of extreme northern Australia and the southern Pacific Ocean. A partial eclipse will be visible in most parts of eastern Australia and New Zealand. (NASA Map and Eclipse Information (Note: This event is not visible in the Philippines.)

November 17, 18 : Leonids Meteor Shower

The Leonids is one of the better meteor showers to observe, producing an average of 40 meteors per hour at their peak. The shower itself has a cyclic peak year every 33 years where hundreds of meteors can be seen each hour. The last of these occurred in 2001. The shower usually peaks on November 17 & 18, but you may see some meteors from November 13 – 20. The crescent moon will set early in the evening leaving dark skies for what should be an excellent show. Look for the shower radiating from the constellation Leo after midnight, and be sure to find a dark location for viewing.

November 27 : Conjunction of Venus and Saturn

These two bright planets will be within 1 degree of each other in the morning sky. Look to the east around sunrise.

December 3 : Jupiter at Opposition

The giant planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph Jupiter and its moons.

December 11 : Saturn, Venus, Mercury and the Crescent Moon at Predawn

Check the eastern sky about an hour before dawn to see this magnificent celestial display of the three planets and the thin lunar crescent.

Eastern sky at around 5 am | Manila

December 13, 14 : Geminid Meteor Shower

Considered by many to be the best meteor shower in the heavens, the Geminids are known for producing up to 60 multicolored meteors per hour at their peak. The peak of the shower usually occurs around December 13 & 14, although some meteors should be visible from December 6 – 19. The radiant point for this shower will be in the constellation Gemini. This year the new moon will guarantee a dark sky for what should be an awesome show. Best viewing is usually to the east after midnight from a dark location.
