Many astronomy enthusiasts gathered last Friday, August 13 to observe the peak of the annual Perseids Meteor Shower as well as the beautiful display of planets after sunset.
My astronomy organization here in the Philippines, the UP Astronomical Society (UP AstroSoc), held a public observation for this event at the Sun Deck of PAGASA Astronomical Observatory in the University of the Philippines – Diliman. It was attended by around 30-40 guest who patiently waited for the Perseids despite the partly cloudy sky before midnight. The org’s telescopes were also set up so the attendees could view the planets Venus and Jupiter (with 4 of its moons!) which were visible during that night.
This observation was even featured in a news report of GMA’s Saksi, a local news program. Below is the video containing interviews by some of the attendees:
Note: It was mentioned in the report that the planetary conjunction (planets appear near one another in the sky) is difficult to see without the use of telescopes. This is not true because seeing planetary groupings require a wider field of view (extent of the observable area) of the sky. Telescopes offer more details but have smaller field of view than our eyes.
I and two of my colleagues, Andre Obidos and Bea Banzuela, chose to observe from Marikina City. The skies were also cloudy there but we were still lucky enough to see and capture the ghostlike Moon with the planet Venus an hour after sunset in the west. Mars and Saturn however, were too dim to shine through the clouds.
We waited for the constellation Perseus (where the meteors would seem to radiate from) to rise around midnight but the sky was still full of clouds. We went out again around 3am but we saw nothing except for an overcast night sky with just a few bright stars like Altair, Vega and Deneb and the planet Jupiter which was nearly overhead. Following are some our images which were taken using Canon PowerShot SX 20:
Other members of the organization went to different locations to help facilitate the other public observations of the event.

Due to the coming of the rainy season here in the Philippines, having a clear night sky this month was almost impossible. Nonetheless, observers were still thankful that the clouds cleared up for even a short while, allowing them to see 4 or more of those beautiful bright streaks of light with the planets. 😀
According to the IMO measurements the 2010 Perseid meteor shower was above normal with a peak activity of over 100 meteors per hour under optimal viewing conditions but not spectacular. In the coming nights the Perseids will still be visible, but with fewer and fewer meteors night by night.

Wondering what to do on this Friday night? Dance with the meteors and the planets. 😀
The University of the Philippines Astronomical Society (UP Astrosoc) invites everyone to its public observation of the spectacular Perseid Meteor Shower and planetary grouping of Mars, Venus, Saturn and Mercury on August 13th (Friday) from 6pm to 6am of the following day at the PAGASA Observatory Sun Deck in the University of the Philippines Campus, Diliman.
Likewise, the UP-Los Banos Astronomical Society (UPLB Astrosoc) will hold an Astronomy Camp entitled “Astra La Vista: The First Encounter” also on the 13th at D.L. Umali Hall in UP Los Banos, Laguna. Aside from observing the Perseids and the planetary grouping, this event will be its launching activity as well.
So don’t forget to mark your calendars on this date, list down your wishes and watch these events from your local areas.
Let’s pray for clear skies 🙂
A lot of Filipino amateur astronomers including me 😀 are excited for this month’s sky display.
For Philippine observers, the annual Perseids Meteor Shower which often shows 50 meteors per hour will be observed with its peak on the late night of August 12-13. The Perseids appear to radiate out from the constellation Perseus, which is located in the eastern horizon during August.
2010 is a great year for the Perseids. This year, the slender waxing crescent moon will set at early evening, leaving a dark sky for this year’s Perseid show.
The Perseids tend to strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn. These meteors are often bright and frequently leave persistent trains. The Perseid Meteor Shower is famous for its Earthgrazers –meteors that approach from the horizon and skim the atmosphere overhead like a stone skipping the surface of a pond. Earthgrazers are long, slow and colorful; they are among the most beautiful of meteors.
The source of the shower is Comet Swift-Tuttle. Although the comet is nowhere near Earth, the comet’s tail does intersect Earth’s orbit. We glide through it every year in August. Tiny bits of comet dust hit Earth’s atmosphere traveling 132,000 mph. At that speed, even a smidgen of dust makes a vivid streak of light–a meteor–when it disintegrates.
Friday the 13th will never be unlucky for sky observers on this night. Those who plan to watch the Perseids will also have the chance to see a beautiful planetary grouping before the radiant rise in the East.
Coincidentally, on August 13 at around 7pm the crescent Moon will join the groupings of Mars, Venus, Saturn and Mercury in the western horizon.
Happy observing and Clear Skies to all!
