Evening Twilight

Venus dominates the evening twilight.  Look tonight, a few minutes after sundown, toward the western horizon to spot a bright “star”.  That’s Venus.  Our sister world continues a slow but steady shift eastward each night.  Venus glides toward the southwest moving from Virgo to Libra without gaining altitude.  Tonight, look to the left of Venus about 7 ½ degrees as the twilight darkens a bit, to spy Spica, the brightest star of Virgo.  Venus creeps about a degree per night toward Spica.  On September 1, Venus will be 4 ½ degrees to the right of Spica.  Watch on the nights of September 4-6 to see Venus pass within 1 ½ degrees above Spica.  By September 7th, Venus will have passed Spica by more than 3 degrees.  A skinny crescent Moon joins the widening pair on September 9th.

Mercury makes a poor appearance this month.  An ultra-thin crescent moon will sit about 3 ½ degrees above Mercury on September 8th. Mercury continues hugging the western horizon for about 3 weeks before it slides into the sunset’s glare.

Saturn, Jupiter and Neptune are up all night

Telescope observers can enjoy a trio of gas giants this month. Saturn is now well placed in the south as the sky darkens. Best viewing for Saturn tonight is just after 11 p.m. PDT. By midmonth, observers can enjoy best views of Saturn in the south by 10 p.m. PDT.  About an hour later, Jupiter follows Saturn.  By September 15, Jupiter is best observed by just after 11 p.m. PDT.  Telescope observers should circle September 12,18, and 25 as nights to watch Jupiter’s moon Io creep across the disk of Jupiter.  Europa does the same transits on September 19th and 26th.   Binocular observers should look at Jupiter on September 6th and 20th to see all of the 4 Galilean moons lined up on the east and the west side of Jupiter.

Neptune is visible all night on September 14th.  The most distant gas giant will be more than 2.7 billion miles from earth and shine at a dim 7.8 magnitude in Aquarius.  Look about 30 degrees from bright Jupiter to search for Neptune.  Neptune will be best observed about 2 hours after Jupiter.
