Observation of the June 2010 Partial Lunar Eclipse

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.

Partial Lunar Eclipse of June 26, 2010

The Second eclipse of 2010 which will occur on June 26, will be visible in the Philippines as a partial lunar eclipse.

According to PAGASA, the Philippines will have a chance to see the moon turn red during this event.

The eclipse magnitude will be 54.2 percent and will also be visible primarily in some parts of America, Pacific Ocean, Antarctica, eastern Asia, and Australasia. The eclipse will begin at 4:55 PM Philippine Standard Time (PST) and will end at 10:21 PM (PST).

Following are the eclipse circumstances for Manila observers:

Eclipse Magnitude: 54.2 percent

Penumbral eclipse begins: 4:55 PM

Partial eclipse begins 6:16 PM

Greatest eclipse 7:38 PM

Partial eclipse ends 9:00 PM

Penumbral eclipse ends 10:21 PM

sunset: 6:28 pm

moonrise: 6:24 pm (full at 7:31 pm)

“Lunar eclipses are safe to watch and observers need not use any kind of protective filters for the eyes. A pair of binoculars will help magnify the view and will make the red coloration of the moon brighter,” said PAGASA Administrator Prisco Nilo.

Clear skies everyone and happy observing! 😀
