During this period, the moon reaches its first quarter phase on Monday October 2nd. At that time the moon will lie 90 degrees east of the sun and will be set between 22:00 and 23:00 local daylight saving time (LDST). As the week progresses the waxing gibbous moon will begin to seriously interfere with meteor observing as it approaches its full phase. This weekend, the morning hours will be free of interfering moonlight.
During this period, the moon reaches its new phase on Sunday September 25th. At that time the moon will lie near the sun and will be invisible at night. As the week progresses the waxing crescent moon will enter the evening sky but will set long before the more active morning hours arrive.
During this period, the moon reaches its last quarter phase on Saturday September 17th. At that time the moon will lie 90 degrees west of the sun and will rise between 2300 and midnight.

The AMS received nearly 1200 reports and 10 videos so far about a bright fireball seen from Ireland and the UK.
During this period, the moon reaches its full phase on Saturday September 10th. At that time the moon will lie opposite the sun and will lie above the horizon all night long. As the week progresses the waning gibbous moon will rise later in the evening, affording some dark sky meteor viewing between dusk and moon rise.
During this period, the moon reaches its first quarter phase on Saturday September 3rd. At that time the moon will lie 90 degrees east of the sun and will set between 23:00 and midnight Local Daylight Saving Time (LDST).
