During this period, the moon reaches its new phase on Tuesday September 7th. At that time the moon lies near the sun and is invisible at night. This weekend the waning crescent moon will rise shortly before dawn and will not interfere with meteor observing. Late in this period the waxing crescent moon will enter the evening sky but again it will set near the end of dusk and will not interfere with meteor observing.

During this period, the moon reaches its last quarter phase on Monday August 30th. At that time the moon lies 90 degrees west of the sun and rises near 23:00 local summer time (LST) on Sunday August 29th. During this period evening skies will be free of interfering moonlight, but morning observers must take care to avoid the moon within their field of view. The moon rises later with each passing night enlarging the window of opportunity to view meteor activity under darker skies.

During this period, the moon reaches its full phase on Sunday August 22nd. At that time the moon lies opposite the sun and remains above the horizon all night long. This is the worst time of the month to try and view meteor activity as the bright moon will obscure all but the brightest meteors. Later in the week there will be a short opportunity to view between dusk and moon rise, but meteor activity during this time is low.

During this period, the moon reaches its first quarter phase on Sunday August 15th. At that time the moon lies 90 degrees east of the sun and sets near 23:00 local summer time (on Aug. 14). As the week progresses the waxing gibbous moon sets later and later, diminishing the available time of dark sky with each passing night.

During this period, the moon reaches its new phase on Sunday August 8th. At that time the moon lies near the sun and is invisible at night. As the week progresses the waxing crescent moon enters the evening sky but will set before the more active morning hours arrive.
