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 August 7-13, 2010

Meteor activity kicks into high gear in August as seen from the northern hemisphere. The main reason for this activity surge is the Perseid shower that peaks on August 13. This shower is active most of the month and remains above the level of the sporadic background for a week centered on August 13. The sporadic activity is also increasing as seen from the northern hemisphere and is now nearly double the rates from just three months ago. As seen from south of the equator, meteor rates are still decent but falling rapidly. The sporadic rates seen at the beginning of the month will be twice as high as those seen during the last days of the month.

Meteor Activity Outlook for July 17-23, 2010

After several months of low activity the meteor rates for both hemispheres see a marked increase in July. In the northern hemisphere the change is not noticeable until mid-month when several southern radiants, the Perseids, and sporadic rates all increase in activity. Southern rates are good all month long.

During this period the moon reaches its first quarter phase on Sunday July 18th. At this time the moon will be located ninety degrees east of the sun and will set near 0100 for those living in mid-northern latitudes.

Meteor Activity Outlook for July 10-16, 2010

After several months of low activity the meteor rates for both hemispheres see a marked increase in July. In the northern hemisphere the change is not noticeable until mid-month when several southern radiants, the Perseids, and sporadic rates all increase in activity. Southern rates are good all month long.

During this period the moon reaches its new phase on Sunday July 11th. At this time the moon will be located near the sun and will be invisible at night.

Meteor Activity Outlook for June 26-July 2, 2010

After several months of low activity the meteor rates for both hemispheres see a marked increase in July. In the northern hemisphere the change is not noticeable until mid-month when several southern radiants, the Perseids, and sporadic rates all increase in activity. Southern rates are good all month long. It should be noted that enhanced activity from the June Bootids is possible during this period. The maximum is expected near 0200 Universal Time on June 28th. This corresponds to 2200 or 10pm EDT on Sunday evening June 27th.

Meteor Activity Outlook for June 5-11, 2010

June is another slow month for meteor activity. There are no major showers active in June and only the Antihelion source can be counted on for continuous activity. Even the Antihelion is located so far south this time of year that rates rarely exceed two per hour as seen from the northern hemisphere. Sporadic rates reach their nadir in June as seen from the mid-northern hemisphere (45 N).

Meteor Activity Outlook for May 22-28, 2010

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. The only other showers active this month are the weak Nu Cygnids, the Eta Lyrids, and the Antihelion radiant. These will add only 1-2 meteors per hour to the total count. Sporadic rates are low but steady as seen from the mid-northern hemisphere (45 N).
