10/01/2014 – Ephemeris – Let’s start off the month with a look at the bright planets

October 1, 2014

Ephemeris for Wednesday, October 1st.  The sun will rise at 7:40.  It’ll be up for 11 hours and 42 minutes, setting at 7:23.   The moon, at first quarter today, will set at 12:43 tomorrow morning.

Let’s check out the bright planets for this week.  Mars and Saturn are in the southwestern sky at 8:30 p.m. with Mars above the equally bright and red star Antares with Saturn a ways right of them and as high in the sky as Antares.  Saturn will set at 9:16 p.m.  Mars is in the constellation of Ophiuchus as astronomers draw constellation boundaries, though it looks to be in Scorpius.  Mars will set at 10:04.  In the morning sky brilliant Jupiter will rise in the east-northeast at 3:02 a.m.  Venus will rise about a half hour before the sun, so it will not be visible.  On the 25th of this month Venus will be in superior conjunction with the sun, that is it will move behind the sun, and will then enter the evening sky.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.

The first quarter Moon tonight at 8:30 p.m. with some interesting locations. Created using Virtual Moon Atlas.

Points of interest on the moon tonight:

  • Alpine Valley – This is a fault valley some 79 miles (130 km) long and 7 miles (11 km) wide through the lunar Alps.
  • Straight Wall – This is a fault that runs north-south on the moon and is only seen either one day after first quarter or one day after last quarter.  It is 67 miles (110 km) long and 900 feet (300 meters) high.  But instead of being a wall, it has only a 7 degree slope, which explains its brief appearance.  Tonight it will cast a shadow.  One day after last quarter the sun will shine directly on the slope, which is covered by lighter material and will show as a bright line.
