Longer Nights during Autumnal Equinox starting September 22, 2012

Wednesday, 12 September 2012 0 comments

Longer Nights will be experienced during Autumnal Equinox occuring on September 22, 2012.

At an equinox, the Sun is at one of two opposite points on the celestial sphere where the celestial equator (i.e. declination 0) and eclipticintersect. These points of intersection are called equinoctial points: classically, the vernal point (RA = 00h 00m 00s and longitude = 0º) and the autumnal point (RA = 12h 00m 00s and longitude = 180º). By extension, the term equinox may denote an equinoctial point.

Here's a Press Release from PAGASA-DOST:
Stars and Constellations

Philippine nights will be longer as the Sun approaches the celestial equator. Autumnal equinox will occur on September 22 when day and night will have equal length on Earth.

The rich band of constellations and stars along the Milky Way from the constellations Cygnus, the Swan, in the north to Sagittarius and Scorpius in the south, begin to give way this month to fainter constellations, many of them with watery associations such as the constellations of Capricornus, the Sea Goat, Aquarius, the Water Bearer and Pisces the Fish.
