A penumbral eclipse of the moon will occur on Nov. 30 and will be observed in northwestern Europe, the Americas, Oceania, and most of Asia, including the Philippines, according to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).

It said the eclipse begins when the moon enters penumbra at 3:32 p.m. and ends at 7:53 p.m. (Philippine Standard Time). The full Moon will enter its maximum penumbral eclipse around 5:30 p.m.

A penumbra refers to a partially shaded outer region of a shadow that an object casts, PAGASA explained.

A penumbral eclipse occurs when the Moon passes through the faint penumbral portion of the Earth’s shadow, which causes the moon to appear slightly darker than usual.

"The lunar surface is not completely shadowed by the Earth’s umbra (darkest part of a shadow). Instead, observers can see only the slightest dimming near the lunar limb closest to the umbra," PAGASA said.

"The eclipse may be undetectable unless at least half of the Moon enters the penumbra," it added.

International astronomers said that about 82 percent of the Moon's face will turn a shade darker during the maximum phase of this eclipse.

The lunar eclipse is safe to watch and observers need not use any kind of protective filters for the eyes.

Earlier this year, the Philippines witnessed a penumbral lunar eclipse on June 6 and an annular solar eclipse on June 21.
