Activity Outlook

Weekly Meteor Activity Outlook articles by Bob Lunsford. Bob gives outlooks to upcoming meteor activity about once a week. He features showers from the working list of meteor showers as well as suspected radiants. Please refer only to the radiants of the Working list of visual meteor showers in observing reports.

Meteor Activity Outlook for May 23-29, 2015

During this period the moon reaches its first quarter phase on Monday May 25th. At this time the moon will be located 90 degrees east the sun and will set near 0100 local daylight saving time (LDT) as seen from mid-northern latitudes. As the week progresses the window of opportunity between moon set and dawn shrink with each passing night. By Friday there will only be one hour of dark sky available just before dawn. The estimated total hourly meteor rates for evening observers this week is near 2 for observers situated at mid-northern latitudes and 3 for observers viewing from the southern tropics (latitude 25 S.).

Meteor Activity Outlook for May 16-22, 2015

During this period the moon reaches its new phase on Monday May 18th. At this time the moon will be located near the sun and will be invisible at night. As the week progresses the moon will enter the evening sky but will set during the early evening hours and will not cause any problems for viewing during the active morning hours. The estimated total hourly meteor rates for evening observers this week is near 3 for observers situated at mid-northern latitudes and 4 for observers viewing from the southern tropics (latitude 25 S.). For morning observers the estimated total hourly rates should be near 7 for observers situated at mid-northern latitudes and 12 for observers viewing from the southern tropics.

Meteor Activity Outlook for May 9-15, 2015

During this period the moon reaches its last quarter phase on Monday May 11th. At this time the moon will be located 90 degrees west of the sun and will rise near 0100 local daylight saving time (LDT). This weekend the waning gibbous moon will rise near midnight LDT and spoil the dark sky for the remainder of the night. As the week progresses the conditions improve as the moon wanes and rises later each night. The estimated total hourly meteor rates for evening observers this week is near 2 for observers situated at mid-northern latitudes and 3 for observers viewing from the southern tropics (latitude 25 S.).

Meteor Activity Outlook for May 2-8, 2015

May is a fairly slow month for meteor activity. The Eta Aquariids are very active the first two weeks of the month then fade as the month progresses. Unfortunately the nearly full moon will spoil the maximum of the Eta Aquariids this year. The only other showers of note this month are the Eta Lyrids and the Anthelion radiant. These will add only 2-3 meteors per hour to the total count. Sporadic rates are low but steady as seen from the mid-northern hemisphere (45 N). Sporadic rates seen from the tropical southern latitudes (25 S) are strong and remain so the entire month.

Meteor Activity Outlook for April 25-May 1, 2015

During this period the moon reaches its first quarter phase on Saturday April 25th. At this time the moon will be located 90 degrees east of the sun and will set near 0100 local daylight saving time (LDT). As the week progresses the moon will interfere more and more with meteor observing as it waxes and sets later each morning. By the end of the week the moon will be in the sky most of the night making meteor viewing difficult as the glare from the nearly full moon obscures all but the brightest meteors. The estimated total hourly meteor rates for evening observers this week is near 2 for observers situated at mid-northern latitudes and 3 for observers viewing from the southern tropics (latitude 25 S.).

Meteor Activity Outlook for April 18-24, 2015

During this period the moon reaches its new phase on Saturday April 18th. At this time the moon will be located near the sun and will not be visible at night. Next week the waxing crescent moon will enter the evening sky but it will set prior to midnight and will not interfere with viewing during the more active morning hours. The estimated total hourly meteor rates for evening observers this week is near 3 for observers situated at mid-northern latitudes and 4 for observers viewing from the southern tropics (latitude 25 S.). For morning observers the estimated total hourly rates should be near 10 for observers situated at mid-northern latitudes and 13 for observers viewing from the southern tropics.
