Full moon,Jupiter from dusk till dawn August 5
Tonight is Wednesday,Aug 05 2009.
The moon turns full today at 7:55 p.m. Central Daylight Time (8:55 Eastern Daylight Time; 6:55 p.m. Mountain Daylight Time; 5:55 p.m. Pacific Daylight Time). Astronomically speaking, the moon is full at the instant that it’s most directly opposite the sun for the month. For general reference, however, we can say the moon is full all night tonight.
The full moon rises at sundown today. Watch for the Full Sturgeon Moon to climb over your southeast horizon shortly after sunset. About a half hour thereafter, the blazing planet Jupiter follows the moon into the sky. Evening’s two brightest celestial luminaries keep each other company for the rest of the night.
The August full moon is often called the Sturgeon Moon in North America. The Sturgeon Moon harks back to the bygone centuries when this large fish roamed plentifully in the Great Lakes and Hudson Bay. The August full moon is also known as the Green Corn Moon or the Grain Moon.
The August full moon always resides in front of the constellation Aquarius the Water Bearer or Capricornus the Sea-goat. In 2009, the full moon beams in front of Capricornus. However, the moonlit glare washes this rather faint constellation from the sky tonight.
The moon and Jupiter climb upward during the evening hours. Around midnight, the moon and Jupiter swing to the summit of their travels in southern sky. Then the moon and Jupiter descend westward during the wee hours after midnight. They appear low in the southwest at morning dawn.
The moon and Jupiter travel westward throughout the night for the same reason that the sun travels westward during the day. The Earth rotates from west-to-east on its axis. Therefore, the sun, moon, planets and stars appear to move westward across the sky.
