May 9/10 Meteors

Rain and clouds have been the rule in the Tucson area lately. After 1.5 months of no rain, we got 0.30″ at the house. Mind you, I’m not complaining. Especially since the nights are rarely completely cloudy as was the case over the past two nights. Both nights saw a few hours of clear skies resulting in some meteor detections.

While the most active shower is still the fading Eta Aquariids (ETA), more Eta Lyrids (ELY) were detected last night. The ELYs are from Comet IRAS-Araki-Alcock which passed very close to Earth (0.03 au) in 1983 and reached 1st magnitude. It is a long-period comet currently on an orbit with a ~1000 year period. The ELY are a minor shower but produced a few meteors each year in early May.
