After the Quadrantids Meteor Shower last January 4, the skies will once again be illuminated by another major astronomical event—the Penumbral Lunar Eclipse.
Eclipses come in pairs
A solar eclipse is always paired with a lunar eclipse. A solar eclipse only happens during the new moon, while a lunar eclipse occurs during the full moon. For an eclipse to occur, the new and full moons have to take place within the eclipse season, wherein the Earth, Sun, and Moon are perfectly aligned. This happens twice a year, about six months apart.
What is a Penumbral Lunar Eclipse?
On January 11, 2020 at 1:07 a.m., the Penumbral Lunar Eclipse will be visible in the country. It occurs whenever the Earth passes between the Moon and the Sun, blocking out sunlight and casting a shadow on the Moon’s surface.
Unlike other types of eclipses, a Penumbral Lunar Eclipse is more subtle and much more difficult to observe. According to Fred Espenak, an American Astrophysicist, about 35% of all eclipses are penumbral. Another 30% are partial eclipses, while the remaining 35% are total eclipses of the moon.
Where will the Penumbral Eclipse be visible?
The eclipse will be visible in Africa, Oceania, Asia, Europe, and Northern America.
In Manila, the Penumbral Lunar Eclipse starts at 1:07 a.m., reaching its peak at 3:11 a.m. and ending at 5:12 a.m. The next eclipse for the year will be visible on June 6.
