An annular solar eclipse will occur on May 9-10, 2013 (depending on your location). During an annular eclipse, the Moon is near its farthest distance from Earth (i.e., near its apogee) so it appears slightly smaller than the Sun’s disk. Since the Moon doesn’t cover the Sun completely, this leaves a bright ring of sunlight surrounding the Moon’s disk, often called the “Ring of Fire” effect. About 95% of the solar disk will be eclipsed by the Moon.
The path of annularity of the eclipse passes through parts of North Australia, SE Papua New Guinea, Solomon Islands, Kiribati, provided the weather cooperates. Partial eclipse will be seen in a much broader path, which includes other parts of Australia, Eastern Indonesia, Oceania and Southern Philippines.
Time table Worldwide
The eclipse can be observed from 6:08 am until 7:34 am in the Philippines. For local observers, please check the gallery below to give you and idea on how the eclipse would look like for selected localities. Other locations nearby will also see similar views.
Partial eclipse as seen from various locations in the Philippines at maximum eclipse, 6:41 a.m. local time. Simulated in Stellarium. Hover your mouse over an image to view the location.
PAGASA indicated the areas where the eclipse can be observed, including Sorsogon, Masbate, Roxas City, Puerto Princesa City, Cebu, Tacloban, Dumaguete, Surigao, Cagayan de Oro, Iligan, Zamboanga, Hinatuan, Cotabato, Jolo, Davao, and General Santos. It also created a table of local times for viewing the eclipse for the above-mentioned locations.
Note that the eclipse is not visible in Luzon except in the southern tip.
Viewing the Eclipse SAFELY
For observers along the path of the eclipse, astronomers recommend using either a professionally manufactured solar filter in front of a telescope or camera, or eclipse-viewing glasses that sufficiently reduce the sun’s brightness and filter out damaging ultraviolet and infrared radiation. NEVER attempt to observe the partial or annular phases of any eclipse with the naked eye. Failure to use appropriate filtration may result in permanent eye damage or blindness!
To view the eclipse safely, Fred Espenak (www.mreclipse.com) compiled here a list of the acceptable and non-recommended filters for visual observation.
Acceptable filters for unaided visual observations: aluminized polyester specifically designed for solar viewing, shade 12 and 14 welding filters, black polymer filters (Thousand Oaks Solar Shield 2000 and Rainbow Symphony Polymer), and two layers of fully exposed and developed silver-bearing black and white film negative. For photographic and visual use, particularly with binoculars or telescopes, acceptable filters include: aluminized polyester specifically designed for the purpose, and Questar and Thousand Oaks T1 and T2 glass filters. The Thousand Oaks T3 filter should be used with extreme care for photographic use only.
Not recommended: metal-coated polyester that is not specifically intended for solar observation, smoked glass, floppy disk media, black color transparency (slide) film, floppy disk media, and compact disks (because of the inconsistent quality of the metal coating).”
For those who won’t be able to observe the eclipse from their location, you may still watch via live webstreaming of the event.

Clear skies and happy viewing!
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!
Some parts of the world will be able to greet the first part of the new year with a Partial Solar Eclipse on the morning of Tuesday, January 4, 2011. This will be visible from most of Europe, the northern half of Africa, the Middle East and Western Asia. Sadly, this won’t be visible to the Philippines. The next eclipse that we will be able to witness will be the Lunar Eclipse on June 15 (eclipse at moonset) and the more spectacular Total Lunar Eclipse on December 10 which has all its stages visible to Philippine observers.
Four partial solar and two total lunar eclipses take place in 2011. According to NASA Eclipse Website, this 4:2 combination of solar and lunar eclipses in a single year is rather rare with only six cases during the 21st Century (2011, 2029, 2047, 2065, 2076 and 2094).

A solar eclipse can only happen at new moon. When the moon totally covers over the sun, it’s called a total solar eclipse. However, since the moon only blocks out part of the sun today, it’s a partial solar eclipse. The percentage of sun that gets covered over by the moon depends on your place in the viewing zone. Remember to use proper eye protection when watching a solar eclipse! Here is a post from Sky & Telescope which discusses how to observe a partial solar eclipse safely.
To all other eclipse enthusiasts who won’t be able to observe this event from their own location or who can’t afford to travel to witness this phenomenon, I compiled here a list of links wherein you can watch free live web streaming of the eclipse courtesy of several local astronomical groups.

*The Moon will encroach 60% into the solar disk during thespecial live webcast by the Bareket Observatory. The webcast will takes place from 7.00 to 10.30 UT (GMT) on January 4. An “eclipse timer” on the webcast page will count down the time until first contact – the beginning of the eclipse when the Moon first appears to block the edge of the Sun’s disk – at 7.13 UT.

Clear skies to all!
