"September's Morning and Evening Planet Show, and; A Rare Occultation of Saturn!"

Scheduled air date: 2001 Sep 03-09

Although moving swiftly away from the Earth, the planet Mars is still very bright in the evening sky as it makes its way through the famous "Teapot" asterism within the constellation of Sagittarius.  At the end of this month, it will pass within about one-half degree of the star Nunki.
(Mars's position is shown at 7-day intervals.  Horizon shown is for mid-Northern latitudes.)

The Moon will move past the bright planets Saturn, Jupiter and Venus in the morning skies of next week.  On the 10th it will actually occult—or pass in front of—Saturn for viewers in the western part of North America, on the 12th it will be about one-half degree from Jupiter, and on the 15th it will be within four degrees of Venus.
(Main illustration: shown about an hour before sunrise for mid-Northern latitudes.  Inset: Saturn's path behind the Moon will vary slightly with observer location.)
