I noticed that most of my frequent visitors were searching for the eclipses in the Philippines for 2011. Well then folks, I have listed below the eclipses that could be observed in the Philippines throughout the year. 🙂
Four partial solar and two total lunar eclipses will take place in 2011 but only the lunar eclipses will be visible in the Philippines. These two are both total lunar eclipses which means that during these events, we can actually see the entire disk of the Moon being covered by the Earth’s umbra — thus we can observe a nice Reddish Moon.
Total lunar eclipses are pretty rare events so be sure to plan your observation ahead of time and make the most out of this astronomical experience. (In the Philippines, the last one happened during May 5, 2004)
June 15 Total Lunar Eclipse
It will be visible completely over Africa, and Central Asia, visible rising over South America, western Africa, and Europe, and setting over eastern Asia. In western Asia, Australia and the Philippines, the lunar eclipse will be visible just before sunrise on June 16. (View NASA Map and Eclipse Information)

According to the ALP, “this eclipse is particularly special because the Moon passes almost exactly in front of the center of the Earth’s shadow during totality phase thus giving us local viewers in the Philippines a long totality time of around 100 minutes” (1 hr 40 mins) .
December 10 Total Lunar Eclipse
This eclipse will be visible from all of Asia and Australia, seen as rising over eastern Europe, and setting over northwest North America. (View NASA Eclipse Information)

Because I got too excited for this, I created a video simulation of the entire eclipse using Stellarium. The Moon is at the constellation Taurus during this event.
A lunar eclipse occurs when the moon passes behind the earth so that the earth blocks the sun’s rays from striking the moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, there is always a full moon the night of a lunar eclipse.
Unlike observing solar eclipses wherein you need adequate eye protection, lunar eclipses are safe to watch with the naked eye. 🙂

The partial lunar eclipse last June 26, 2010 was the first of two lunar eclipses in 2010. At maximum eclipse, 53.7% of the moon was covered by the earth’s shadow. Full details of the eclipse can be found in from my previous blog post. I and two of my UP Astrosoc colleagues decided to observe this event and take images from Marikina City.
At first, we were anxious that we would not be able to observe the partial lunar eclipse due to the thick rain clouds covering the whole observation area. The sky was overcast that day and it started raining at around 7pm. Using Stellarium, I located the moon in the western sky, but the clouds blocked even the slightest trace of moonlight.
We decided to transfer to another location within the same area where we could get a better view. There were no objects that could be seen through the thick clouds anyway so we just spent our time looking for a nice spot to observe when the rain stopped. While walking past the street corner, we saw this house that had a two-leveled roof deck, ideal for our observation and high enough not to be blocked by any other building that surrounds it. It was a good place for observation, however we are too shy to approach the owner of that house.
Driven by our willingness to observe this rare phenomenon, we overcame our hesitation and went to that house. Fortunately, the owner of the house allowed us to use the top deck. We had our equipment then, so I think we somewhat looked sincere with our request.
As we went up to the deck, we saw a beautiful view of the city with those little lights from below which reminded me of the stars on a dark night. We began to set up our equipment and prepared for the appearance of Luna. After several minutes, it rained. We stayed under an umbrella and used the spare ones to protect our camera and laptop. We just stayed there to wait though a slight shadow of desperation was coming over us then. The rain just seemed to drag on and on and we were soon thinking of packing up our things and going home.
Luckily, after more than an hour of waiting in the rain while holding on to our hopes by praying, the skies began to clear up. Venus appeared in the west, and the moon finally showed itself to us with its upper part still covered by the umbra. We immediately used the binoculars to make sure that it was not just clouds covering the moon. It was a few minutes past 8pm then, and according to the predicted eclipse activity, the moon would still be eclipsed though we had already missed the maximum.
We took several photos at different settings. We needed to adjust our camera’s settings every now and then because the clouds were moving fast in front of the moon. There were even times when we needed to wait for minutes for the clouds to pass. Good thing that despite the little time left for us to take photos and the thick clouds, we were still able to get nice shots.
We left the place a little past 10pm, when the penumbral eclipse was about to end.
Unfortunately, were not able to witness the maximum eclipse because of the rain. Nevertheless, I still feel so blessed to have been able to take images of this event 😀
We will surely never forget this experience for it deepened our love for astronomy and the sky. We are now more inspired to do astro imaging for the next astronomical event.
Photo details: We took the photos using Canon PowerShot SX20
Post-processing was done using Registax V.5.1 to enhance the lunar features.
