Oct 21/22 Meteors

Last night’s Tucson video data showed a slight decrease in the number of Orionids. The previous two nights saw 52 and 54 meteors, so last night’s 45 is a bit lower. According to all of the naked eye observations submitted to the International Meteor Organization, the peak occurred on Tuesday morning with a ZHR in the mid-40s.

Now that we are passed the peak in Orionid activity, is it too late to observe? Not at all. You still have tonight and perhaps tomorrow night to see a good number of meteors. Though rates will be lower, the Orionids will still produce a half-dozen or so meteors per hour from a semi-dark suburban site. Darker sites will see even more meteors. Remember, you will see no Orionids before 10pm, and it is best to observe after midnight.
