A view of the majestic sunset last October 6, 2011 taken from a windowpane on the 3rd Floor of the Gonzales Hall in UP Diliman. :) I particularly love the crimson-colored sky during this time. Fortunately, I had the camera with me that time and was able to take this image even without a sturdy tripod.
Last October 21, 2011, I attended the International Astronomical Union (IAU) Formal Gala Dinner at the Science Discovery Center in SM Mall of Asia, Pasay City.
Fellow members from my org, UP Astronomical Society; professors and students from different universities namely UPLB, RTU, and DLSU; astronomy educators, and amateur astronomers were also attendees of this gathering.
The event’s theme was ‘Astronomy for Development’. It aimed to educate and promote awareness of Astronomy among Filipinos. It was also to inform the people about the importance of astronomy and to let them know the latest development and innovation in the field.
Speakers were Dr. Rogel Mari Sese, Head of Astrophysics Lab in the Institute of Mathematical Sciences and Physics, UPLB; and Dr. Kevin Govender, the current Director of the IAU Office of Astronomy for Development.
Before proceeding with the talks, a short planetarium show entitled “New Horizons” was played to entertain the audience. It was an all-dome-video experience that features a majestic journey through our celestial neighborhood.
Dr. Sese was the first one to deliver a talk. He discussed several key ideas in pursuing Astronomy as a profession particularly in the Philippines. He further explained that having a career in astronomy is challenging and highlighted a few important points on what in takes to be an astronomer. These, according to him are the following:
- Passion – main motivation for one to learn
- Plan – [Because] the learning journey is long
- Perseverance – main motivation for one to finish
He finished his talk my leaving this inspiring message: “Be passionate and patient. It’s all worth it in the end.”
“Astronomy stretches our imagination.”“Science is about exploring God’s universe.”“Astronomy for a better world.”
A short open forum was eventually held after the talks to allow questions from the audience. A lot of curious questions about astrophysics have been asked by several students until after the formal dinner.
All in all, the event was truly a great and memorable experience.
I’m glad that IAU is still taking its commitment in expanding astronomy development programs in areas where astronomy is still an emerging and minor field (such as in the Southeast Asian (SEA) region), even after the successful International Year of Astronomy (IYA 2009) was over. At the same time, I’m also proud that the Philippines is already taking part in holding activities such as this which enable young astronomers and students in particular, to further develop their interest in the field.
I hope that there would be more scientific collaborations such as this one, in the near future that could stimulate the rapid growth of science among developing societies.
Ad astra per aspera!
Did you know that Halloween is a significant day on the astronomical calendar?
Surprising, isn’t it? Halloween means more than just a day for spooky stuff, costumes and candy treats. This celebration is actually a cross-quarter day which means it falls approximately half way between the Autumnal Equinox, the astronomical start of fall and Winter Solstice, the astronomical start of winter.
It’s no coincidence that Halloween has a dark side. Halloween is believed to have originated with the ancient Celtic harvest festival Samhain. Samhain roughly translates to “summer’s end”. It was the date that signaled the start of winter when most plant life is dead. A season where food would be limited and living conditions would be less than favorable. It was a day of celebration and of dread, the line between the living summer and the dead winter. It was not until middle ages that the day was associated with the Christian holidays of All Saints Day and All Souls Days.
This year’s Halloween has a bit of something for everyone. This is because the eastern sky during late October nights is filled with deep sky treats for stargazers of all types.
For the naked eye observer, the first of the brilliant stars of winter start to peek over the eastern horizon: Capella and Aldebaran. Three of the nearest galactic star clusters are visible to the naked eye: the Pleiades, the Hyades, and the Perseus Moving Cluster.

Happy Halloween! :)
As I prepared to observe the Orionid Meteor Shower last October 22, a nice celestial pairing of the waning crescent Moon (22% full) and the tiny planet Mars greeted my view. These two were roughly 8 degrees apart during this conjunction and were located just slightly above “the Sickle” in Leo. Unfortunately, the glow from the light-polluted city made the 1.2 magnitude Mars (on the upper left of the image) difficult to notice with the naked eye.
Mars appears to be like a plain bright red star right now that rises in the east during the wee hours after midnight. In the months ahead, Mars will brighten and will also rise earlier at night. By December 2011, this planet will climb over the eastern horizon before midnight. In January 2012, it’ll be up by mid-evening, and even sooner on February 2012 evenings.
Mars will come closest to Earth in March 2012. It will be out from dusk till dawn, shining about nine times more brightly than it does at present. Even so, Mars won’t be nearly as bright as the planets Venus or Jupiter.
Despite the 50% chance of a thunderstorm and a full moon, I and my UP AstroSoc friends braved our way to Bataan last August to observe this year’s Perseid Meteor Shower during its peak event.
We stayed at Stella Maris Beach Resort in Bagac to observe overnight.
The sky was totally overcast when we came. Nevertheless, we were fortunate that the Full Moon was already low in the west when the eastern sky cleared up around 3:00 to 5:00 AM just in time for the Perseids.
We were able to spot a few fireballs zooming across the region near Perseus and around the Winter Hexagon. The highest meteor count that we had was 23.
We also got to observe Jupiter (with its Galilean Moons!) and the planet Mars though a friend’s Dobsonian telescope which we fondly call Lulin.
Here are some images of Jupiter taken through afocal method:
We finished our Perseid viewing at dawn and left the place a couple of hours after to tour around Bataan. Some of the places we visited were the Bagac Friendship Tower, Dunsulan Falls in Pilar, and the Dambana ng Kagitingan (Shrine of Valor) at the summit of Mt. Samat.
Mount Samat was the site of the most vicious battle against the Japanese Imperial Army in 1942 during the Battle of Bataan. The shrine there was built as a symbol of courage and gallantry to all Filipino soldiers who shed their blood in defending our beloved country to foreign invaders. I felt honored to have been able to visit this place and pay respect to my fellow Filipinos who died during the war.
Going at the top of Mount Samat was the best experience ever! It felt like I can almost touch the clouds with my two bare hands when I was up there. I also love the cool gentle breeze and the nice view (you can see the whole town of Bataan and the Manila Bay from there). My friends and I were very excited as we climbed up the stairs going up the cross. It was a bit tiring though.
Overall, I consider this trip as one of the most memorable trips I ever had. :) Aside from successfully catching the Perseids despite of the bad weather, we were also blessed with a great opportunity to visit some of the historical places in the country and experience nature at its finest. It was truly a sweet escape!
Thanks to Elaine, Kiel, Bea, Josh, Saeed, Ron and Pinyong for being with me in this endeavor. :)

This contest was held in honor of Global Astronomy Month 2011 last April. Participants used the Observing With NASA portal and MicroObservatoryImage software to create RGB Composite images and Astrocreative images.
MicroObservatory is a network of automated telescopes that anyone can control over the Internet.
The telescopes were developed by scientists and educators at the Harvard-Smithsonian Center for Astrophysics. They are located and maintained at observatories affiliated with the Center for Astrophysics, including the Harvard College Observatory in Cambridge, MA and the Whipple Observatory in Amado, AZ.
Using many of the same technologies that NASA uses to capture astronomical images by controlling telescopes in space, amateur astronomers world-wide can control a sophisticated ground-based telescope from the convenience of any computer. The MicroObservatory remote observing network is composed of several 3-foot-tall reflecting telescopes, each of which has a 6-inch mirror to capture the light from distant objects in space. Instead of an eyepiece, the MicroObservatory telescopes focus the collected light onto a CCD detector (an electronic chip like that in a digital camera) that records the image as a picture file with 650 x 500 pixels.
With these robotic telescopes, people can take images of the Moon, Sun, nearby planets and some deep-sky objects even without having a telescope! :) Cool, isn’t it?
I’ve been using MicroObservatory for over a year now and I have already taken and processed several images using it. Below are some of them:
Congratulations to all the winners of the contest and thank you, MicroObservatory! :)
This year’s Orionids will peak on the evening of October 21/22 . These meteor fragments radiate from the top of Orion’s upraised club, near the Gemini border.
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. As the comet moves through space, it leaves debris in its wake that strikes Earth’s atmosphere most fully around October 20-22. Around this time every year, Earth is more or less intersecting the comet’s orbit.
Meteor specialists have meteor counts for this pass averaging a modest 20 per hour under dark skies. The moonlit glare of the waning crescent Moon, however will probably reduce the numbers somewhat this year.
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.
Clear skies to all and happy viewing! :)

October’s Full Hunter’s Moon nearly coincides with the apogee of the moon’s orbit, or the point at which the moon is farthest from Earth. That makes October’s full moon appear smaller than usual, the opposite of the “supermoon” effect that occurred earlier last March when the moon was full during its closest approach to Earth.
The moon reached its peak fullness at 2:06 a.m. UT last Oct. 12. Shortly thereafter, the moon was at its farthest point from Earth, which it reaches once a month. The moon’s orbit is elliptical rather than perfectly circular, which is why the distance from Earth to the moon varies by tens of thousands of miles depending on the time of month and year. The moon’s orbit is also always slightly changing because of differing effects of the sun’s gravity.
Though we couldn’t notice with our own eyes, the Moon’s apparent size changes throughout the year and this is because of the phenomenon called Lunar libration, or the wobbling of the Moon.
Below is an animation which demonstrates this effect. It shows the geocentric phase, libration, position angle of the axis, and apparent diameter of the Moon throughout the year 2011, at hourly intervals.

I was walking past the Diliman Sunken Garden with someone last October 14 when I caught a glimpse of the Waning Gibbous Moon (94.6% full) close to bright Jupiter. Thank God that after several days of continuous rains, the skies have finally cleared that evening :)
These two objects which both dominate the night sky this month were just less than 15 degrees apart.
I was lucky to have been able to take a few images of this nice celestial conjunction since I always bring the camera with me. It was a bit challenging though, because I didn’t have my sturdy tripod during then to stabilize and elevate the camera.
The streak of light above Jupiter was just a passing airplane which happened to be included in the frame when I was doing the shot.
More photos below…
Special thanks to that someone who kept me company while I was taking photos that evening at the middle of the Sunken Garden. ;)
As summer time has already ended, the constellation Sagittarius, along with the other Summer constellations sets earlier during the month of October.
Sagittarius is believed to have originated with the Babylonians. He was their god of War, and he stands with his bow aimed at the heart of Scorpius, the scorpion. Like Centaurus, he is a half man, half beast creature.
We in modern times may not be able to imagine the stars of Sagittarius as a Centaur. Instead, many stargazers know the stars of Sagittarius as a “Teapot”. This asterism is really easy to recognize.
Sagittarius is an important constellation in that it marks the direction of the center of our galaxy, the Milky Way. It also contains more Messier objects than any other constellation in the sky.
Earlier this evening, I took the chance to take an image of the “Teapot” before it disappears in the night sky. I was also planning to image Scorpius but it was already too low in the south west. As I looked at the image more closely, I began to noticed something interesting. On the right (just above its lid), there is a faint cloud-like patch that resembles the Milky Way. I got surprised. :)
Could it be really possible to see a faint apparition of the Milky Way in this light-polluted suburb?
InOMN is an annual event celebrated world-wide to encourage people to go out and observe Earth’s nearest neighbor in space — the Moon.

The website features activities, educational materials, multimedia and much more!
Meanwhile, the meteor activity of the Draconids (or Giacobinids) is also expected to be at maximum tonight, 8 October 2011 between 16h00m and 21h00m Universal Time (UTC)*. This irregular shower that sometimes produces meteor storms is linked to comet 21P/Giacobini-Zinner. The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky.
The glare of moonlight is sure to interfere with this year’s Draconid shower, but you should try viewing it tonight, anyway, to see if the predicted outburst will occur.
* The predicted date of maximum is the date when the meteoroid density encountered by the Earth is expected to be maximum. Actual maximum local rate observed from a specific area is likely to happen at a different time, depending on your location. Therefore, it is incorrect to just convert the UTC maximum date to local time, as your local circumstances are likely to be different (for example, the radiant not even being visible at the time of nominal maximum!). In the Philippines, the peak activity is expected to occur on October 9 between 12:00 -5:00 AM PHT. The radiant, however will set around 11:00 PM (which means we cannot observe the peak) so it would be best to observe earlier — between 7:00 PM – 11:00 PM.
Looks like the rain will spoil both of these events :( But let’s all try our luck tonight and see what will happen. Clear skies!
As the nights get longer in the northern hemisphere, the skies are filled with good observing opportunities.
Meteor showers, a comet, and Jupiter at opposition are the highlights for October.

Two meteor showers: Draconids & Orionids
The Orionids will peak this year on the evening of October 21/22 . Periodic (76 year orbit) comet 1P/Halley is the source of these meteors. Meteor specialists have meteor counts for this pass averaging a modest 20 per hour, best visible before dawn under dark skies. These meteor fragments radiate from the top of Orion’s upraised club, near the Gemini border. The waning crescent Moon this year should not interfere much with your observing of these shooting stars.
Newly discovered comet Elenin will make its closest approach to the Earth on October 16. The comet was discovered on December 10, 2010 by Russian amateur astronomer Leonid Elenin. It is estimated that the comet will reach 6th magnitude as it makes its closest approach. This will make it just barely visible to the naked eye. With a good pair of binoculars and a little determination, you may be able to get a good look at this new comet during mid October.
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. The giant planet will be a big and bright as it gets in the night sky. A medium-sized telescope should be able to show you some of the details in Jupiter’s cloud bands. A good pair of binoculars should allow you to see Jupiter’s four largest moons, appearing as bright dots on either side of the planet.
This month’s full moon is called Hunter’s Moon because at this time of year the leaves are falling and the game is fat and ready to hunt. This will also be the smallest full moon of the year because it will be near apogee, its farthest point from the Earth.
Mercury-Venus & Moon at minimum separation
This is a wonderful conjunction of 2 planets, the waxing crescent Moon and the red giant star Antares about 30 minutes after sunset on the nights of October 28 & 29th. You will need an unobstructed view low to the SW. Use binoculars or a small telescope to locate challenging Mercury.

This morning, I went outside again at around 4:30 AM to check the sky condition. I’ve been doing this for about a couple of days now in hopes of seeing a clear sky despite the continuous rains over the past few weeks.
It’s really creepy out there — wind’s blowing strong & it’s totally dark! But thank God it wasn’t too cloudy and I was able to do some timelapse photography just before the stars start fading away against the blue sky at dawn.
I’m keeping my fingers crossed for the coming weeks. :) Clear skies!
Hello everyone! :)
It’s been ages since I posted my last entry here. I missed this blog so much.
I’ve been really busy doing and organizing a lot of stuff during the last couple of months that I rarely had time to write. Moreover, the observing conditions were very seldom good because of the rainy season — several typhoons hit the country and it’s too cloudy most of the time.
It is not until towards the end of September that the rainy season in the Philippines will start receding. Its normal termination usually occurs by the end of October.
Anyhow, the coming of October also marks the coming of longer nights in the Philippines. Just last October 1, the Sun rose at 5:46 AM and set at 5:46 PM (Manila time). This day signaled the transition point in nature when the light changes. The days are getting shorter in the Northern Hemisphere — everyone can feel the shortening of the days and sense, innately, that the changes in daylight and darkness are sudden and surprising.
During the equinox last September 23, the length of night and day across the world is nearly, but not entirely, equal. This is because the day is slightly longer in places that are further away from the equator, and because the sun takes longer to rise and set in these locations. The axial tilt of the earth affects the day/night duty cycle most strongly at the poles and has no effect at all at the equator. Equal day and night usually occurs a few days after the equinox. For simplicity, we may assume that it has actually occurred on October 1. Take note that there is really no equal day and night at the equator.
For amateur astronomers, longer nights mean extra hours of uninterrupted stargazing! :)
The fine meteor showers usually come in by October to December of each year. October 2011 has two meteor showers worth getting outside to see — the Draconid meteor shower on the evenings of October 7 and 8 and the more reliable Orionid meteor shower on the mornings of October 20 and 21.
As the Draconids and Orionids kicks off the meteor shower season, observing the night sky would be more fun and interesting.
Clear skies to all!
