During this period the moon will reach its first quarter phase on Thursday November 15th. At this time the half-illuminated moon will be located in the early evening sky and will set near midnight local standard time (LST). This weekend the waxing crescent moon will set during the early evening hours allowing meteor observations under perfect conditions during the more active morning hours.
During this period the moon will reach its new phase on Wednesday November 7th. At this time the moon will be located near the sun and will be invisible at night. This weekend the waning crescent moon will rise during the early morning hours but will not cause any problems viewing meteors as long as you keep it out of your field of view.
During this period the moon will reach its last quarter phase on Wednesday October 31st. At this time the moon will be located 90 degrees west of the sun and will rise between 2200 and 2300 local daylight saving time (DST). This weekend the bright waning gibbous moon will rise during the early evening hours and will spoil the remainder of the night by obscuring all but the brighter meteors.
The estimated total hourly meteor rates for evening observers this week is near 3 for those viewing from the northern hemisphere and 2 for those located south of the equator. For morning observers the estimated total hourly rates should be near 18 as seen from mid-northern latitudes and 13 from the southern tropics. Rates are reduced during this period due to moonlight.
During this period the moon will reach its new phase on Tuesday October 9th. At this time the moon will be located near the sun and will be invisible at night. This weekend the waning crescent moon will rise just before dawn and will not interfere with viewing meteor activity.
During this period the moon will reach its last quarter phase on Tuesday October 2nd. At this time the moon will be located 90 degrees west of the sun and will rise between 2300 (11pm) and 0000 (midnight) local summer time (LST). This weekend the waning gibbous moon will rise during the late evening hours. This will hamper meteor observations the remainder of the night as the bright moonlight will obscure all but the brightest meteors. Conditions improve with each passing night as the moon wanes and rises later.

During this period the moon will reach its first quarter phase on Sunday September 16th. At that time the moon will lie 90 degrees east of the sun and will set near midnight local daylight saving time (LDT). As the week progresses the waxing gibbous moon will set later and later, shrinking the window of opportunity to view meteor activity under dark skies.
During this period the moon will reach its new phase on Sunday September 9th. At that time the moon will lie near the sun in the sky and will be invisible at night. As the week progresses the waxing crescent moon will enter the evening sky but will not interfere with viewing meteor activity.
During this period the moon will reach its last quarter phase on Monday September 3rd. At that time the moon will lie 90 degrees west of the sun in the sky and will rise near midnight local daylight saving time (LDT) as seen from mid-northern latitudes. As the week progresses the waning crescent moon will rise later with each passing night, creating more favorable viewing conditions.
During this period the moon will reach its full phase on Sunday August 26th. At that time the moon will lie opposite of the sun in the sky and will remain above the horizon all night long. As the week progresses the waning gibbous moon will rise during the late evening hours with the moon severely hampering efforts to see meteor activity during the more active morning hours.
During this period the moon will reach its first quarter phase on Saturday August 18th. At that time the moon will lie 90 degrees east of the sun in the sky and will set near midnight local daylight saving time (LDT) as seen from mid-northern latitudes. As the week progresses the waxing gibbous moon will encroach upon the morning hours, limiting the time observers have to view under moonless conditions.
During this period the moon will reach its new phase on Saturday August 11th. At that time the moon will lie near the sun in the sky and will be invisible at night. As the week progresses the waxing crescent moon will enter the evening sky but will not cause much interference for meteor observers, especially during the more active morning hours.
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 will reach its last quarter phase on Saturday August 4th. This is good for evening observations but once the moon rises during the early morning hours, conditions will be less than ideal. These conditions improve with each passing night to where there is little lunar interference at the end of this period.
During this period the moon will wane from it's nearly full phase down to almost half-illuminated. This weekend the moon will rise shortly after dusk and will rise approximately 45 minutes later each night. Although meteor activity is strong this time of year the bright moon will obscure all but the brighter meteors.
During this period the moon will reach it's full phase on Friday July 27th. At that time the moon will be located opposite the sun and will lie above the horizon most of the night. This weekend the waxing gibbous moon will set during the early morning hours allowing a few hours of dark skies in which to watch meteor activity under good conditions.
During this period the moon will reach it's first quarter phase on Thursday July 19th. At that time the moon will be located 90 degrees east of the sun and will set around 0100 local daylight saving time (DST). This weekend the waxing crescent moon will set during the early evening hours and will not interfere with meteor viewing.
Meteor season finally gets going in July for the northern hemisphere. The first half of the month will be much like June with predominately slow rates. After the 15th though, both sporadic and shower rates increase significantly!
The estimated total hourly meteor rates for evening observers this week is 2 as seen from mid-northern latitude (45N) and 3 from the southern tropics (25S). For morning observers the estimated total hourly rates should be near 10 as seen from mid-northern latitudes (45N) and 13 from the southern tropics (25S). Evening rates are reduced due to interfering moonlight.
During this period the moon will reach it's first quarter phase on Wednesday June 20th. At that time the moon will be located 90 degrees east of the sun and will set near 0100 local daylight saving time (LDT). This will cause interference with evening meteor viewing but the more active morning hours will be free of moonlight. This weekend the waxing crescent moon will set prior to midnight allowing good views of the morning activity.
