During this period, the moon waxes from its new phase to nearly 50% illuminated.

During this period, the moon reaches its new phase on Friday July 9th. At that time the moon is located near the sun and is invisible at night. This weekend a bright crescent moon will illuminate the morning sky. Successful meteor watches can still be held at this time as long as you keep the moon well out of your field of view.

During this period, the moon reaches its last quarter phase on Thursday July 1st.

During this period, the moon reaches its full phase on Friday June 25th.

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.
