Jupiter remains well placed for observing this month.  It outshines everything except the Moon and Venus and is therefore easy to find in the south-southwest at dusk.  Venus continues to re-emerge into the evening sky.  Although it is low in the west southwest during evening twilight, Venus outshines everything in the sky except the Sun and the Moon, so viewers with clear views to the west southwest should be able to find it right after sundown.  Saturn has also emerged into the morning sky; face east at dawn to see it.  Late October is a good time to observe Mercury before dawn.  Greatest elongation (that is, greatest apparent distance from the Sun) is October 22.  You can look for about a week to either side of that date; Mercury is slightly brighter in the days following greatest elongation if it’s at dawn.  Mars is lost in the Sun’s glare this month and will remain out of sight until 2009.

The Big Dipper happens to be to the lower left of the North Star at dusk this month; you’ll need a clear northern horizon to get a good look at it.  Sagittarius, the Archer, known for its ‘teapot’ asterism, is in the southwest (Jupiter is in Sagittarius).  Look for the enormous Summer Triangle, consisting of the stars Deneb, Vega, and Altair, high in the west.   As familiar summer patterns shift to the west, the constellations of autumn take center stage.  The Great Square of Pegasus is high in the east at dusk.  The star in its upper left hand corner is also the head of Andromeda.  Facing north, you’ll see five stars in a distinct ‘M’ like shape—this is Cassiopeia, the Queen.  Her stars are about as bright as those in the Big Dipper, and she is directly across the North Star from that Dipper.  In fall, while the Dipper is low, Cassiopeia rides high.

Our George Observatory remains closed while Brazos Bend State Park recovers from Ike.  The park hopes to reopen by October 11, and there is hope that our annual Astronomy Day at the observatory, set for Saturday, October 18, will proceed as scheduled.   Astronomy Day features special presentations and activities for the whole family from 3pm to 10:30pm.  Surf to www.astronomyday.org for more information. 

Sunday, November 2, is the first Sunday of that month.  Accordingly, we ‘fall back’ to Standard Time that morning at 2:00am. (We go from 1:59 am back to 1:00 am).  Don’t forget to set your clocks back one hour on Saturday night, November 1.  Enjoy your extra hour of sleep!

  1. what is the bright star/planet that currently appears very near the moon in the evening sky?

  2. That would be Jupiter. The Moon is now passing by Jupiter; it appeared to Jupiter’s lower right last night (10/6/2008) and will be to the lower left of Jupiter tonight (10/7/2008). The Moon then moves out of the picture. Jupiter, however, outshines all stars in the south southwest at dusk all month long.
