During this period the moon reaches its last quarter phase on Sunday September 22nd. At this time the half-illuminated moon will rise near 23:00 local summer time (LST) and will remain in the sky the remainder of the night. Successful meteor observations can be obtained by simply viewing in a direction with the moon at your back. The moon will become less of a problem with each successive night as its phase wanes and it rises later in the morning. The evening sky is unaffected by moonlight but still produces less activity than the morning hours.
