During this period, the moon reaches its last quarter phase on Thursday July 1st. This weekend the nearly full moon will lie above the horizon most of the night, spoiling viewing conditions for meteor observers. As the week progresses, evening conditions improve as the moon rises later with each passing night. This allows a small window of opportunity to view under dark skies between dusk and moon rise.

During this period, the moon reaches its full phase on Friday June 25th. This weekend the waxing gibbous moon will set during the early morning hours allowing a few hours of viewing meteor activity under a dark sky between moon set and dawn. This window of opportunity shrinks with each passing night and by midweek the time of moon set and dawn will be simultaneous.

During this period, the moon waxes from a thin crescent to nearly one-half illuminated. It will be limited to the evening sky during this entire period and will not interfere with the more active morning hours.

During this period, the moon reaches its new phase on Thursday June 10th. On this date the moon is located near the sun and is invisible at night. This weekend the waning crescent moon will rise during the early morning hours but will not interfere with viewing meteor activity as long as it is not within your field of view.

During this period, the moon reaches its last quarter phase on Wednesday June 2nd. On this date the moon is located 90 degrees west of the sun and rises near 02:00 local summer time (LST). This weekend the waning gibbous moon will rise during the early evening hours and will create difficult conditions for view meteor activity the remainder of the night.
