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 August 10-16, 2013

During this period the moon reaches its first quarter phase on Tuesday August 13th. At this time the moon is located ninety degrees east of the sun and will set between 2300 and midnight for locations in mid-northern latitudes. This weekend the waxing crescent moon will not interfere with observing as it is very thin and will set shortly after dusk and will not interfere with observing during the more active morning hours. The estimated total hourly meteor rates for evening observers this week is near five for observers located in the northern hemisphere and three for those viewing south of the equator.

Meteor Activity Outlook for August 3-9, 2013

Meteor activity kicks into high gear in August as seen from the northern hemisphere. The main reason for all this activity is the Perseid shower that peaks on August 12. This shower is active most of the month and remains above the level of the sporadic background for a week centered on August 12. The sporadic activity is also near maximum as seen from the northern hemisphere and is now more than 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 continue their downward slide and the Perseid radiant does not rise high into the sky as seen in the southern hemisphere so rates from this shower are greatly reduced when compared to the northern hemisphere.

Meteor Activity Outlook for July 27-August 2, 2013

During this period the moon reaches its last quarter phase on Monday July 29th. At this time the moon is located ninety degrees west of the sun and will rise near midnight local daylight time (LDT) as seen from mid-northern latitudes. This weekend the bright gibbous moon will interfere with observing during the more active post midnight hours. As the week progresses the waning crescent moon will still cause interference but the circumstances will improve with each passing night. The estimated total hourly meteor rates for evening observers this week is near five for observers located in the northern hemisphere and three for those viewing south of the equator.

Meteor Activity Outlook for July 20-26, 2013

During this period the moon reaches its full phase on Monday July 22nd. At this time the moon is located opposite the sun and will be in the sky most of the night as seen from mid-northern latitudes. As the week progresses the waning gibbous moon will rise later during the evening hours, but will still be in the sky during the more active morning hours, causing considerable interference with meteor viewing. The estimated total hourly meteor rates for evening observers this week is near two no matter your location. For morning observers the estimated total hourly rates should be near six no matter your location.

Meteor Activity Outlook for July 13-19, 2013

During this period the moon reaches its first quarter phase on Monday July 15th. At this time the moon is located ninety degrees east of the sun and will be in the sky until midnight local daylight time (LDT) as seen from mid-northern latitudes. As the week progresses the waxing gibbous moon will set later during the morning hours, interfering with morning observations. The estimated total hourly meteor rates for evening observers this week is near three no matter your location. For morning observers the estimated total hourly rates should be near fourteen as seen from mid-northern latitudes and thirteen as seen from mid-southern latitudes.

Meteor Activity Outlook for July 6-12, 2013

During this period the moon reaches its new phase on Monday July 8th. At this time the moon is located near the sun and is not visible at night. As the week progresses the waxing crescent moon will enter the evening sky but will set long before the more active morning hours arrive. 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 sixteen 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.
