The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Wednesday at 2:09 a.m. the moon would reach its perigee or point in the moon's orbit nearest to Earth. The forthcoming full moon has 357,016,803 kilometers nearest to Earth this year. It will appear 14 percent bigger and 30% brighter than a regular full moon, hence the name "supermoon." But, according to the National Aeronautics and Space Administration, clouds or the opposing glare of urban lights can easily obscure a 30% difference in brightness. PAGASA noted that the supermoon is simply a modern astrological term coined by Richard Nolle, describing it as "a new or full moon that occurs when the moon is within 90% of its closest approach to Earth in a given orbit." In astronomy, it is called a "perigee full moon," or a full moon that is closer to Earth than normal. Earlier, PAGASA said a supermoon could trigger a slightly higher-than-usual tides. It explained that the supermoon affects the height of tides, but will be low as normal waves and may not cause flooding. There is much more gravitational pull when the moon is at perigee or close to earth, which induces higher tides or greater variation in high and low tide. Filipinos can see supermoon from home comfort. It can be seen from naked eyes with clear skies.
