"The Sky This Week" is on summer vacation until August 24.  Here are some important dates and events to keep an eye on for the next couple of weeks.

 

First Quarter Moon: 2010 August 16  2:14 pm EDT      

Full "Sturgeon" Moon: 2010 August 24  1:05 pm EDT

 

The waxing crescent Moon is close to Venus, Mars, Saturn on the evening of August 13.  The three planets are low in the southwest during evening twilight.  Venus passes Mars between August 20 and 23.

 

The Perseid Meteor Shower peaks on the evening/night of August 12/13.  Look for up to 50 - 100 very swift meteors per hour from a dark sky location.  The Moon sets in Washington at 9:23 pm EDT, so it will not interfere with the shower.  Before midnight look for long trails from meteors striking the atmosphere at a shallow angle.  After midnight look for more meteors with shorter trails as Earth rotates into the meteoroid stream.  The "radiant" is located in the northeastern sky between the constellations of Perseus and Cassiopeia.  Meteors from the shower are visible for several days before and after the peak.

 

Jupiter rises at around 10:00 pm EDT early in the period.  By the end of August he rises an hour earlier.
