Meteor Activity Outlook for January 26 – February 1, 2013

The following is a slightly edited version of Bob Lunsford’s excellent weekly summary of meteor activity. The original version can be found at the American Meteor Society’s site.

During this period the moon reaches its full phase on Sunday January 27th. At this time the moon will be located opposite the sun and will be in the sky all night long.  As the week progresses the moon will rise a little later each evening but there is little meteor activity to be seen during the dark evening hours. The estimated total hourly meteor rates for evening observers this week is near two for observers located at mid-northern latitudes and one for observers in mid-southern latitudes. For morning observers the estimated total hourly rates should be near eight from the mid-northern hemisphere and four from the mid-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. Rates are reduced during this entire period due to intense moonlight.

The radiant (the area of the sky where meteors appear to shoot from) positions and rates listed below are exact for Saturday night/Sunday morning January 26/27. These positions do not change greatly day to day so the listed coordinates may be used during this entire period.

The table below presents a condensed version of the expected activity this week. Rates and positions are exact for Saturday night/Sunday morning . Details of each shower will again be provided next week when the situation with interfering moonlight improves.
