Meteor Showers

There are no major meteor showers this month...
September is a month with the best sporadic rates and a few mysterious minor showers.
The Alpha Aurigidsareactive from Aug. 25 to Sept. 5, normally with a ZHR of 10. this year it may be quite active

The Delta Aquarids are active September 5 thru October 10, with a ZHR of 6. It is on view until dawn. Faint, swift meteors are likely and the brighter ones may leave persistent trains.
These two form part of what is known as the Auriga-Cassiopiea-Perseus-Aries-Triangulum radiants, active from late August until mid-October.

The Piscids, active September 1 - 30, have a ZHR of 3.

The Sextanids are active September 9 through October 9. Though, this one is more of a radio/radar shower.

A new meteor shower, called the September Taurids, might peak this month on the evening of September 13 - 14. The exact date and time of maximum activity, however, are uncertain. The radiant, which lies between the Pleiades and Hyades star clusters, produces only 7 meteors per hour, with an average brightness of magnitude 2.7.

On this day, the Sun rises directly in the East, and sets directly in the West. At the South Pole, the Sun will begin to rise after six months of darkness.

Watch out for the zodiacal lights, also known as the false dawn, which maybe visible about two hours before sunrise from dark sites during the latter part of September.
