December 10, 2011 Total Lunar Eclipse

Despite the rain and an overcast sky, we were thankful that for a brief period of time God permitted us to have a glimpse of the Red Moon during the total eclipse of the moon last December 10, 2011.

The moon was nearly high overhead during the totality phase of the eclipse and was located in the constellation Taurus. Totality lasted for about 51 mins.

I didn’t get decent shots of the moon during this event but I was really happy to have witnessed it. 🙂

After a short while, the clouds began to move away and we had a clear view.

The red tint of the eclipsed Moon is created by sunlight first passing through the Earth’s atmosphere, which preferentially scatters blue light (making the sky blue) but passes and refracts red light, before reflecting back off the Moon. Differing amounts of clouds and volcanic dust in the Earth’s atmosphere make each lunar eclipse appear differently.

Moon at 11:51 pm. A 22 degree lunar halo formed around the moon just before it exited the umbral eclipse phase.

By the way, I observed this event together with my friend and UP AstroSoc orgmate, Bea Banzuela. We were eating a cold dinner (literally!) from the rooftop of their house in Marikina City while checking the sky and taking photos of the moon.

Bea used her sophisticated camera, Panasonic Lumix DMC-GH2 (with telephoto lens) in capturing lunar images. Below is one of the images she took:

The lunar features in this image are more recognizable. 🙂 I love that camera! Haha! Thanks Bea, for allowing me to repost this.

Observing the ‘Red Moon’ from Seven Suites Hotel Observatory

I began my preparation to observe the June 16, 2011  Total Lunar Eclipse as soon as I’ve learned about it several months ago.

It was a relatively rare opportunity to observe a Total Eclipse of the Moon — not to mention that the duration of totality of this eclipse will be one of the longest in 100 years (totality lasted for 100 minutes, from 3:22 am until around 5:02 am PHT).

I immediately checked the eclipse circumstances available in the NASA eclipse website and estimated the location of the Moon for each phase using Stellarium, so as to choose the best place to observe the event. I also reviewed the previous photos I’ve taken to see which places have a clear view of the southwest sky — the region where the Moon was mostly located during the course of the whole eclipse event. After considering a few sites, I came down to only three choices — the PAGASA Observatory in UP Diliman, a place along San Miguel by the Bay and at the Seven Suites Hotel Observatory in Antipolo.

Dropping the other two choices, I observed at the Seven Suites.

Since I still have a class to attend the following morning, observing at San Miguel by the Bay was the least good option. It surely was a nice place to observe as it has a very clear western horizon (which will enable me to catch a glimpse of the eclipsed moon setting at the bayside), but traveling would be a bit of a hassle for me because it was too far. The most convenient choice was actually to observe at the PAGASA Observatory. It’s just a walking distance away from my college and most of my orgmates in UP AstroSoc were there, too. However, I was worried that the buildings surrounding the observatory might block the view of the Moon when it gets too low during the last phases.

Through Mr. Ramon Acevedo or Kuya Ramon —  an alumnus of my astronomy org UP AstroSoc — the manager of Seven Suites allowed me and a few more orgmates  to observe from Seven Suites for free 🙂 Thanks, Kuya Ramon!

Seven Suites is the first and only hotel observatory in the Philippines.  As it is situated along the hillside route of Sumulong Highway in Antipolo City (not too far away from UP Diliman), it offers a breathtaking view of Manila by night — a stunning view of the metropolis, its city lights and the dazzling night sky. It also houses a 12”diameter Dobsonian which is the fourth largest telescope in the country.

We arrived at Seven Suites at about two hours before the start of the penumbral eclipse. Upon reaching the roof deck, we marveled at the awesome cityscape just below us.

Despite the rainy weather forecast, thank God it didn’t rain a bit the whole night. Only a few patches of clouds could be seen floating amid the moonlit sky.

A colorful lunar corona surrounded the Moon before the eclipse. The blue spot appeared because of the lens flare.

A few minutes past midnight, a group of mediamen from a local TV Network came to join us to cover the event. Someone from GMA contacted me earlier that day via Twitter  for an interview regarding the eclipse. He told me that he learned about me after seeing a post which linked my astro blog.  He further asked me where I will  be observing the event and I told him of my plan and the time of the eclipse . I also added that another group of my orgmates in UP AstroSoc will also be observing the event from the PAGASA Observatory. After our conversation, he said that they will send a group there. And they did. Kuya Ramon was also notified of their coming.

I shied away from the camera when they started doing the interview. Any how, my other orgmates were also there and they answered the interview questions adequately. 🙂

All of us were excited to witness the eclipse. But before it started, a bright fireball zoomed in to our view. It came from the northeast direction, near the Summer Triangle so we guessed that it could be a June Lyrid.

At the time of the penumbral eclipse, no visible changes in the moon’s brightness can be easily recognized until it slowly become dimmer a few minutes before the umbral phase. By about 2:30 AM, a small part of the Moon on its upper left limb was already being covered by the Earth’s shadow. This chunk grew larger and larger after several minutes until finally only a small sliver of the Moon remained visible. The Moon entered totality at 3:22 AM. Just before the light on the Moon totally disappeared, an apparent reddening of the lunar disk took place. It became more and more obvious to the eye until the whole lunar disk was transformed to a blood-red orb hanging above among the stars. It was a breath-taking view.

I also created two montage composed of the images of the Moon during different stages of the eclipse. In the second photo, the images were taken by about 5-10 minutes apart.

Totality ended at 5:02 AM. Unfortunately, the fifth contact (end of the partial eclipse) and sixth contact (end of the penumbral eclipse) could not be observed from the Philippines since the moonset was at 5:30 AM.

Here is a time-lapse video of the setting eclipsed Moon which I made using Windows Movie Maker. The transition of the images were quite slow because each frame can only be separated by a minimum of 1 second when using WMM. Can anyone suggest a better video editing software (preferably with a small size on disk) that can be used by amateurs?

5:01 AM — The Moon was about to exit Totality

Only a small part of the Moon remained visible as it continuously sank near the horizon. A few minutes before sunrise, we noticed another nice atmospheric phenomenon — anticrepuscular rays.

5:14 AM — a small part of the Moon was visible above the city skyline. The pink lines above were anticrepuscular rays.

Anticrepuscular rays are similar to crepuscular rays, but seen opposite the sun in the sky during sunrise or sunset.

We packed up and prepared to leave at around 6:00 in the morning. I was starting to feel tired during then but I resisted sleepiness as I still need to attend my class. One of us even said that we were already like zombies during that moment because of sleep-deprivation. Haha!

From L to R: Kuya Ramon, Miguel, Aaron, Me and Carmen. Elaine left earlier than us that’s why she’s not in the picture 😦
BRAAAAAINS!

Our efforts didn’t go fruitless, anyway. Seeing the Red Moon was truly a priceless experience. Besides, I was also happy that I was finally able to set foot in Seven Suites after a few years. Yes, I’ve been planning to visit the place ever since. but some circumstances seemed to hindered me most of the time.

All photos were taken using Nikon D3000 DSLR camera. Thank you, Nicky for lending me your camera.  🙂 

My fellow UP AstroSoc members who observed at the PAGASA Observatory were also successful in observing and documenting this event. God is really great, we were not clouded out. 🙂 Like us, they also got interviewed during the event.

The news reports including the interviews came out later that day. The person from GMA who contacted me texted me that the video coverage was already being aired. I wasn’t able to catch it on the television but it was now available online. You can watch the video of the interview from here.

The lunar eclipse was the talk of the town during the whole day. Eclipse pictures, videos and articles flooded the Internet. Moreover, Google also featured the lunar eclipse that just took place  through its regular Google Doodle. So if you happened to take a peek at your Google homepage last June 16, you should have seen a playable lunar eclipse photos, like the one below:


This “live” doodle showed a live feed of the lunar eclipse from images from robotic telescope service Slooh. During the eclipse, visitors to Google.com can see a dial at the bottom of the image moving left to right, going through the various stages of the eclipse, before settling on the current feed.

On the other hand, clicking on the doodle will take you to the top search results about the 16 June Total Lunar Eclipse. Some friends told me that the link to my blog about the visible eclipses in the Philippines in 2011 was on the 4th spot. 🙂 And indeed, I got a lot of site visitors during that day. Thanks to all who dropped by and left their wonderful comments.

‘Til the next Total Lunar Eclipse on December. 🙂 Ad astra!


The Blood Red Moon During Maximum Totality

The Moon (and the city) during maximum totality at 4:13 AM (PHT)

A marvelous apparition of a blood-colored or deep red Moon stunned a lot of Philippine sky viewers  during the Total Lunar Eclipse last June 16, 2011. The totality time lasted for about 1 hour and 40 minutes.

At the time of the totality – when the Moon passes through the Earth’s umbral shadow – the entire disk of the Moon turns vibrant red. The Earth’s atmosphere which acts like a filtered lens bends red sunlight into our planet’s shadow and scatters out blue light. It’s the same reason why sunrises and sunsets appear reddish. If Earth had no atmosphere, its shadow would be pitch black and the eclipsed moon would be invisible.

According to some astronomers, this eclipse was the darkest lunar eclipse in almost 100 years  because the centers of the sun, the earth and the moon were nearly be on one straight line.

I’m still editing the other eclipse photos. Will post the rest of them including my observation report soon. 🙂

This photo was taken from the very nice Seven Suites Hotel Observatory in Antipolo.
Camera used was Nikon D3000 (48mm, f/5.6, 30-sec exp. at ISO 200)

A Tip on Lunar Photography:

As you can observe, the image was a bit out-of-focused. I had a hard time focusing on the Moon as subject during that time because I didn’t have a good telephoto lens that could’ve made the Moon appear clearer and larger. Telephoto lenses are  well-designed for photographing distant subjects like the Moon. However, those are very expensive. Wide angle lenses used in landscape photography such as this makes the moon look even  smaller than how you had visualized it in the scene.


Red Moon in June: Public Stargazing and Total Lunar Eclipse Observation

The University of the Philippines Astronomical Society (UP AstroSoc) invites everyone in observing the spectacular total lunar eclipse on June 15 – 16!

After the moon got super huge last March 2011, this coming June 16 2011, the moon will once again be spectacular to watch as it turns red because of the total lunar eclipse.


The first of the two eclipses of 2011 will occur on the said date and it will start at around 1:25AM and will end at around 7AM but the fun part where it turns red will be on its totality at around 4AM.

What is more special about this eclipse is that this will be the darkest lunar eclipse in almost 100 years as the centers of the sun, the earth and the moon would nearly be on one straight line. This also means that the Moon will pass deeply through the Earth’s Umbral Shadow which will make the totality phase last about 100 minutes.

This event is open to all. Come and invite your family and friends, and witness this wonderful sky show.

Clear skies, everyone!


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)

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.

Note: All eclipse stages are visible in the Philippines. 😀

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. 🙂

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! 😀
