Eclipses Visible in the Philippines During 2011

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)

Enjoy! :)

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)

Below are the complete eclipse circumstances as well as predicted times of each eclipse phase (in PHT or UT+8) computed by Fred Espenak of NASA. Altitude and azimuth approximations were provided by the Astronomical League of the Philippines (ALP).

TIME  (PHT) ALTITUDE AZIMUTH
Moon Enters Penumbra 01:24:27am 45 deg 212 deg S
Moon Enters Umbra 02:22:57am 37 deg 225 deg S
Moon Enters Totality 03:22:29am 26 deg 234 deg SW
Maximum Totality 04:13:44am 16 deg 240 deg SW
Moon Exits Totality 05:02:42am 06 deg 244 deg SW
Moonset 05:30:00am 00 deg 246 deg SW
Moon Exits Umbra (not visible) 06:02:14am ———- ———–
Moon Exits Penumbra (not visible) 07:00:41am ———- ———–
Notes:
*The indicated times above are on June 16.
*Sunrise is at 05:26 AM.

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) .


The Moon will be located in the constellation Ophiuchus during this eclipse. Click to enlarge image.

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)

Contact Times : (All in PHT= UT +8)

TIME  (PHT) ALTITUDE AZIMUTH
Moon Enters Penumbra 19:33:36 31 deg 72 deg
Moon Enters Umbra 20:45:43 59 deg 72 deg
Moon Enters Totality 22:06:16 64 deg 67 deg
Maximum Totality 22:31:49 69 deg 63 deg
Moon Exits Totality 22:57:24 75 deg 55 deg
Moon Exits Umbra 00:17:58 79 deg 321 deg
Moon Exits Penumbra 01:29:57 65 deg 292 deg
Note: All eclipse stages are visible in the Philippines.  :D

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.

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. :)

  4. Hello and thank you for this information. I could not find anywhere else that listed the times and what phases can be expected from the Philippines.
    I have my camera setup to take some photos and video. If I alter the shutter speed and use the max zoom, I can get some pretty clear photos. However, I am sure you can get better photos with a camera and telescope.
    As I sat outside watching the moon enter the penumbra phase, the sky was clear except for a few wisps of clouds. Then a huge dark cloud floated in and filled the sky. Here’s hoping the umbra phase and actual eclipse have clearer skies.
    I will post links to my photos as soon as I have got them off my camera later tonight.

    Thanks again

    Hi, Liked your informative website. Just a little correction for you. PST is Pacific Standard Time. PHT is Philippines Time. I used to live in PST (in California).

    hi,
    i just wanted to ask.. you indicated that the greatest eclipse on the june15 eclipse is around 4am PST on june16, so that means it will be at 8pm on june16 in the philippines which is GMT+8?

    thanks in advance for your reply! :)

    • Hi Moon,

      The greatest eclipse of the June Lunar Eclipse will happen at June 15, 2011 20:12:27 UT. Converting that to Philippine Standard Time (PST) which is equivalent to UT+8, the greatest eclipse will be witnessed at 04:12:22 AM on June 16, 2011 from the Philippines.

      Hope you find this helpful. Cheers!
