The estimated total hourly meteor rates for evening observers this week is near 3 as seen from mid-northern latitudes (45N) and 2 as seen from tropical southern locations (25S). For morning observers the estimated total hourly rates should be near 15...
During this period the moon will reach its first quarter phase on Sunday November 26th. At this time the half-illuminated moon will lie 90 degrees east of the sun and will set near 2300 (11pm) local standard time (LST). The moon will interfere with evening observing but will set before the more active morning hours arrive. Toward the end of this period the waxing gibbous moon will remain in the sky most of the night, obscuring all but the brighter meteors.
During this period the moon will reach its new phase on Saturday November 18th. At this time the moon will lie near the sun and will be invisible at night. Next week the waxing crescent moon will enter the evening sky but will not interfere with meteor observing.
During this period the moon will reach its last quarter phase on Saturday November 11th. At this time the half-illuminated moon will rise near midnight local standard time (LST) and will remain above the horizon the remainder of the night. The moon will be bright but successful meteor watches can be conducted if you face away from the lunar glare. Viewing circumstances improve with each passing night as the moon's phase wanes and it rises later in the morning.
As the week progresses the evening hours become more favorable for viewing as the moon rises later in the night. Unfortunately the evening hours are usually slow with rates rarely surpassing 5 per hour. This is a good time to try an catch a bright Taurid meteor or perhaps a rare Andromedid!
As seen from the northern hemisphere, meteor rates continue to be strong in November. While no major activity is expected this month, the two Taurid radiants plus the Leonids keep the skies active.
During this period the moon will reach its first quarter phase on Friday October 27th.

This weekend the waxing crescent moon will set shortly after dusk and will not interfere with meteor observing...
The Orionids, like all meteor showers, are named after the constellation in which they appear to come from, which in this case is Orion. Remnants from this shower come from Halley's Comet, officially designated 1P/Halley.
For morning observers the estimated total hourly rates for this week should be near 17 as seen from mid-northern latitudes and 16 from the southern tropics. The actual rates will also depend on factors such as...
During this period the moon will reach its last quarter phase on Thursday October 12th. At this time the moon will be located 90 degrees west of the sun and will rise near 2300 local daylight saving time (LDT). This weekend the waning gibbous moon will rise during the late evening hours creating difficult conditions to see meteor activity the remainder of the night due to the moon's glare.
During this period the moon will reach its full phase on Thursday October 5th. At this time the moon will be located opposite the sun and will lie above the horizon all night long. This weekend the waxing gibbous moon will set during the early morning hours, allowing meteor observers a few hours of dark skies before the first light of dawn.
During this period the moon will reach its first quarter phase on Wednesday September 27th. At this time the moon will be located 90 degrees east of the sun and will set near 0100 local summer time (LST).

During this period the moon will reach its last quarter phase on Wednesday September 13th. At this time the moon will be located 90 degrees west of the sun and will rise near midnight local daylight time (LDT) as seen from mid-northern latitudes. This weekend the waning gibbous moon will rise during the late evening hours and will ruin the prime meteor viewing hours with its intense moonlight.
September offers longer nights in the northern hemisphere that tend to be less hazy than those experienced in mid-summer. In the sky, no major showers are visible from either hemisphere but the northern hemisphere enjoys the advantage of higher sporadic rates.
During this period the moon will reach its first quarter phase on Tuesday August 29th. At this time the half-illuminated moon will be located 90 degrees east of the sun and will set near midnight for observers located at mid-northern latitudes. This weekend the waxing crescent moon will set during the late evening hours allowing the more active morning hours to be free of interfering moonlight.
