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 June 20-26, 2015

During this period the moon reaches its first quarter phase on Tuesday June 23rd. At this time the moon will be located 90 degrees east of the sun and will set near midnight local daylight time (LDT) for observers located in mid-northern latitudes. This upcoming weekend the waxing crescent moon will set during the late evening hours and will not interfere with meteor observing during the more active morning hours. 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 June 13-19, 2015

During this period the moon reaches its new phase on Tuesday June 16th. At this time the moon will be located near the sun and will be invisible at night. This upcoming weekend the waning crescent moon will rise just before the onset of dawn and will not interfere with meteor observing. 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 9 for observers situated at mid-northern latitudes and 12 for observers viewing from the southern tropics.

Meteor Activity Outlook for June 6-12, 2015

During this period the moon reaches its last quarter phase on Tuesday June 9th. At this time the moon will be located 90 degrees west the sun and will rise near 0100 local daylight saving time (LDT) as seen from mid-northern latitudes. This upcoming weekend the waning gibbous moon will rise during the late evening hours and will compromise meteor observing the remainder of the night due to its intense glare. As the week progresses conditions will improve as moon rise occurs later in the morning and the moon's phase wanes producing less light. 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 30-June 5, 2015

June is another slow month for meteor activity. There are no major showers active in June and only the Anthelion source can be counted on for continuous activity. Even the Anthelion radiant is located so far south this time of year that rates rarely exceed two per hour as seen from the northern hemisphere. Sporadic rates continue to remain slow as seen from the mid-northern hemisphere (45 N). As seen from the southern tropics (25 S) sporadic rates continue to be strong this month.

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.
