May 10, 2013 Annular Solar Eclipse
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.
