MANILA (UPDATE) - A bigger and brighter moon will light up the sky on Tuesday evening, PAGASA said.
A "supermoon" appears when the moon orbits closest to Earth during its full phase, according to the astronomical agency. It appears 14 percent larger and 30 percent brighter than the usual full moon, it earlier said.
The moon is expected to reach its closest point with the Earth at around 11 p.m. Tuesday, said PAGASA weather specialist and research assistant Bernard Punzalan.
The term is astrological in origin and has no precise astronomical definition, PAGASA said.
"The real association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with an increased risk of events like earthquakes and volcanic eruptions, but no such link has been found," PAGASA said.
