Meteor Activity Outlook for May 25-31, 2013

During this period the moon reaches its full phase on Saturday the 25th. At this time the moon will rise shortly after dusk and set shortly before dawn as seen from mid-northern latitudes. With the full moon in the sky nearly all night, this weekend will be a poor time to try and view meteor activity. Circumstances improve slightly as the moon wanes and rises later with each passing night. Unfortunately the moon will still be above the horizon during the more active morning hours during this entire period. The estimated total hourly meteor rates for evening observers this week is near two as seen from the northern hemisphere and three as seen from south of the equator.

Meteor Activity Outlook for May 18-24, 2013

During this period the moon reaches its first quarter phase on Saturday the 18th. At this time the half-illuminated moon will set near 0100 local daylight time (LDT), allowing the remainder of the night to be free of interfering moonlight. As the week progresses this window of dark sky shrinks as the moon sets later with each passing night. The estimated total hourly meteor rates for evening observers this week is near one as seen from the northern hemisphere and two as seen from south of the equator. For morning observers the estimated total hourly rates should be near seven as seen from the northern hemisphere and fifteen as seen from the southern hemisphere.

Meteor Activity Outlook for May 11-17, 2013

During this period the moon waxes from its new phase to nearly fifty percent illuminated. This will limit moonlight to the evening hours during the first portion of this period and up to 2am by Friday May 17. The estimated total hourly meteor rates for evening observers this week is near two as seen from the northern hemisphere and three as seen from south of the equator. For morning observers the estimated total hourly rates should be near thirteen as seen from the northern hemisphere and twenty as seen from the southern hemisphere. The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness and experience in watching meteor activity.

Meteor Activity Outlook for April 27-May 3, 2013

During this period the moon reaches its last quarter phase on Thursday May 2nd. At this time the moon is located ninety degrees west of the sun and rise near 0200 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 severely hamper attempts at meteor observing the remainder of the night. The estimated total hourly meteor rates for evening observers this week is near three as seen from the northern hemisphere and four as seen from south of the equator. For morning observers the estimated total hourly rates should be near five as seen from the northern hemisphere and eight as seen from the southern hemisphere.

Meteor Activity Outlook for April 20-26, 2013

During this period the moon reaches its full phase on Thursday April 25th. At this time the moon is located opposite the sun and will lie above the horizon all night long. This weekend the waxing gibbous moon will set during the late morning hours and allow a very short period of dark skies for meteor observing. The estimated total hourly meteor rates for evening observers this week is near three as seen from the northern hemisphere and four as seen from south of the equator. For morning observers the estimated total hourly rates should be near seventeen no matter your location. The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness and experience in watching meteor activity.

Meteor Activity Outlook for April 13-19, 2013

During this period the moon reaches its first quarter phase on Wednesday April 17th. At this time the moon is located ninety degrees east of the sun and sets near 0100 local daylight time (LDT). This weekend the waxing crescent moon will set during the late evening hours and will not cause any problems for meteor observing. The estimated total hourly meteor rates for evening observers this week is near three as seen from the northern hemisphere and four as seen from south of the equator. For morning observers the estimated total hourly rates should be near ten from the mid-northern hemisphere and fifteen from the mid-southern hemisphere.
