During this period, the moon reaches its last quarter phase on Saturday July 31st. At that time the moon lies 90 degrees west of the sun and rises near midnight local daylight saving time (on August 1st). As the week progresses the waning crescent moon rises later each morning, allowing a better view of the active morning sky as glare from the moon subsides.
During this period, the moon phase wanes from 100 percent illuminated down to nearly one-half illuminated. This weekend the moon lies opposite the sun and is above the horizon all night long. As the week progresses the waning gibbous moon rises later each night, allowing early evening observing under dark skies later next week.
The Perseids are often the most impressive Meteor Shower of the year for the Northern Hemisphere. The Perseid meteor shower offers a consistently high rate of meteors every year and it occurs in August when the temperatures are usually nice enough for a night under the stars!
During this period, the moon reaches its first quarter phase on Saturday July 17th. At this time the moon lies near 90 degrees east of the sun and sets near midnight local daylight saving time (LDST). As the week progresses the waxing gibbous moon enters the morning sky and will begin to interfere with morning meteor observing. By the end of the week the nearly full moon will be in the sky nearly all night long making meteor observing difficult at best.

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. As the week progresses the moon becomes thinner and less of a problem until it disappears entirely into the morning twilight late in the period.
