During this period, the moon reaches its first quarter phase on Sunday June 28th. At this time, the moon is located 90 degrees east of the sun and sets near 01:00 local summer time (LST). As the week progresses the waxing gibbous moon remains longer in the morning sky with each passing night. This narrows the opportunity to view meteor activity under dark conditions from many hours early in the period to almost nil late in the period.

During this period the moon reaches its new phase on Monday June 22nd. At this time, the moon is located near the sun and it invisible at night. As the week progresses the waxing crescent moon will enter the evening sky but will not interfere with meteor observing.

During this period the moon reaches its last quarter phase on Saturday June 13th. At this time the moon will rise near 02:00 local summer time (LST) and will remain in the sky the remainder of the morning. This will compromise late morning viewing but successful meteor observations can still be attempted if one keeps the moon out of their field of view. As the week progresses the waning crescent moon will rise later each morning, becoming less of a problem with each passing night.

During this period the moon’s phase wanes from full to nearly half illuminated. As the week progresses the waning gibbous moon will rise later each night, providing a small window of dark skies between dusk and moonrise. Unfortunately, meteor activity during this time of night is low, but this is offset by the opportunity for younger observers to view the dark evening sky prior to bedtime.
