Oct 19/20 to 22/23 Meteors

The night of October 21/22 marked the peak of this year’s Orionids shower. For observers around the world the display was hampered by a Full Moon which never left the night sky. Here in Tucson, the sky was mostly cloudy as a cut-off low brought some light rain. Still, there were enough clear patches to count quite a few meteors.

Visual reports submitted to the International Meteor Organization suggest a peak ZHR of ~40-50 per hour. Of course, ZHR rates are only observed under perfectly dark conditions. With the nearly Full Moon and the usual issue of light polluted skies, the actual observed rate was much lower.
