Here's a look at the most promising skywatching events of August 2011:
Moon Phases
Sat., August 6, 7:08 a.m. EDT
First Quarter Moon
The First Quarter Moon rises around 3 p.m., and sets around midnight.
Sat., August 13, 2:57 p.m. EDT
Full Moon
The Full Moon of August is known as the Grain Moon. In Algonquian it is known as Sturgeon Moon. Other names are Red Moon, Green Corn Moon, Lightning Moon, and Dog Moon. In Hindi it is known as Narali Poornima or Raksha Bandhan. Its Sinhala (Buddhist) name is Nikini Poya. The Full Moon rises around sunset and sets around sunrise, the only night in the month when the Moon is in the sky all night long. The rest of the month, the Moon spends at least some time in the daytime sky.
Sun., August 21, 5:54 p.m. EDT
Last Quarter Moon
The Last or Third Quarter Moon rises around 11 p.m. and sets around 2 p.m. It is most easily seen just after sunrise in the southern sky.
Sun., August 28, 11:04 p.m. EDT
New Moon
The Moon is not visible on the date of New Moon because it is too close to the Sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise. It is visible low in the west an evening or two after New Moon.
Observing Highlights
All Month, evening twilight
Comet Elenin
Comet Elenin will be well placed in evening twilight for observation with binoculars and small telescopes all month. It will rise from 10th magnitude at the beginning of the month to 6th magnitude by the end of the month, moving from Leo into Virgo.
