Oct 17-24 Meteors

The past week witnessed the annual peak of the Orionid meteor shower. The Orionids are the result of dust created by Comet Halley over 2000-3000 years ago. Visual observers recorded peak ZHRs of only 20-25 meteors per hour. This is less than the peak from the last three years with rates of 30-50 per hour and a huge step down from 2007 when rates as high as 70 per hour were seen.

Unfortunately I missed most of the shower. For three nights was observing some of the objects that create meteor showers rather than the shower itself. The plan was to leave my meteor camera in auto mode but things didn’t work out that way. As a result my system missed three nights of the Orionid peak. I’ll have to figure out how to prevent this in the future.

    Wondering if there was a meteor shower over California today, October 27, around 7am? I am postive I saw my first ever meteor shower this morning but can’t find anything on it. People at work said they were plane but the train and direction were not planes.

    Thanks for any reply.
