The Sky This Week - Thursday October 22 to Thursday October 29
Morning sky looking north-east showing Mars near the Beehive cluster at 4:00 am local daylight saving time (3:00 am non-daylight saving) on Thursday October 29. Click to embiggen.
The First Quarter Moon is Monday October 26.
Mercury is currently not visible.
Saturn is low in the morning sky this week. It is a difficult object in the twilight, but becomes easier during the week as it rises.
Jupiter is easily seen as the brightest object in the evening sky. Jupiter is big enough to be appreciated in even the smallest telescope. If you don't have a telescope to view Jupiter, why not go to one of your local Astronomical Societies or Planetariums open nights? Jupiter's Moons are readily visible in binoculars or a small telescope. The waxing Moon is near Jupiter on Tuesday October 27.

In the morning, Venus and Mars are visible in the eastern sky. Red Mars heads for the the constellation of Cancer and by the end of the week is near the Beehive cluster.
Bright white Venus is very close to the horizon, but is still readily visible in the dawn twilight if you have a clear, unobstructed horizon. During the week Venus comes even closer to the horizon.
The northern horizon at 4:00 am daylight saving time (3:00 am non-daylight saving). The Orionid Meteor Radiant is marked with a cross (click to embiggen)
The Orionids are a worthwhile meteor shower, best seen between 3-5 am (daylight saving time), the radiant being just under Betelgueuse, the bright red star in Orion. This year the best viewing is the morning of the 22nd, when between 4-5 am you should see about a meteor every 3 minutes. However, you should see some decent meteors on the morning of the 23rd as well. To check your local rates, go to the meteor flux estimator page and choose 8 Orionids, your location and type of skies (and make sure to set the date to 2009).
