Meteor Activity Outlook for 27 February-2 March 2018

During this period the moon will reach its full phase on Thursday March 1st. At that time the moon will lie opposite the sun and will lie above the horizon all night long. This weekend the waxing gibbous moon will set shortly after midnight allowing the meteor observer to view under dark conditions the remainder of the night. This window of opportunity will shorten by about an hour with each passing night until the moon lies above the horizon all night long later in the week.

The meteor overflew the provinces of Albacete, Murcia and Alicante. It began over the province of Albacete at a height of around 101 km, and ended over Alicante at an altitude of about 32 km. The event was recorded in the framework of the SMART Project (University of Huelva) from the astronomical observatories of Calar Alto (Almería), La Sagra (Granada), La Hita (Toledo) and...

Meteor Activity Outlook for 10-16 February 2018

During this period the moon will reach its new phase on Thursday February 15. At that time the moon will lie near the sun and will be invisible at night. This weekend the waning crescent moon will rise during the late morning hours and will not interfere with meteor observing. The estimated total hourly meteor rates for evening observers this week is 3 as seen from mid-northern latitude (45N) and 5 from the southern tropics (25S). For morning observers the estimated total hourly rates should be near 10 as seen from mid-northern latitudes (45N) and 17 from the southern tropics (25S). 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. Note that the hourly rates listed below are estimates as viewed from dark sky sites away from urban light sources. Observers viewing from urban areas will see less activity as only the brighter meteors will be visible from such locations. 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 February 10/11. These positions do not change greatly day to day so the listed coordinates may be used during this entire period. Most star atlases (available at science stores and planetariums) will provide maps with grid lines of the...
