Two astronomical events are expected to brighten up the sky this month of June in the presence of the penumbral lunar eclipse and annular solar eclipse, the state weather bureau said.
According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) astronomical diary, the penumbral lunar eclipse will occur on June 6, while the annular solar eclipse will be on June 21.
The penumbral lunar eclipse will be visible in the country starting from 1:45 a.m. to 5:04 a.m.
“A penumbral eclipse occurs when the moon passes through the faint penumbral portion of the earth’s shadow. The lunar surface is not completely shadowed by the earth’s umbra (darkest part of a shadow),” according to PAGASA.
Observers can only see the slightest dimming near the lunar limb closest to the umbra. The eclipse may be undetectable unless at least half of the moon enters the penumbra, it added.
While the annular solar eclipse will be observed in the Philippines as a partial solar eclipse.
“An annular eclipse happens when the moon is farthest from Earth. Because the moon is farther away from Earth, it seems smaller and does not block the entire view of the sun, thus creating a “ring of fire” effect,” explained PAGASA.
The northernmost areas of Luzon will have a good view of the partial solar eclipse, having an eclipse obscuration of up to 91% while the Visayas and the Mindanao areas’ eclipse obscuration ranges from 52 to 66% and 43 to 58%.
An eclipse obscuration is the fraction of the sun’s surface area occulted or covered by the moon, according to PAGASA.
The public is advised to never look at the sun directly during any type of solar eclipse as looking at the sun is dangerous and can damage eyes.
