Apr 26/27 to May 15/16 Meteors

April/May/June are usually clear months in Tucson and this year is setting up to be no different. Though bouts of cirrus are common, every night but one has been clear enough to allow the detection of a few meteors.

The past few weeks have seen a couple of showers come and go. Two minor showers, the Nu Cygnids and Northern May Ophiuchids, produced only 2 meteors apiece. These showers are recent discoveries and little is known about each. The Eta Lyrids produced 1-2 meteors per night at its best. This shower is produced by the long-period Comet IRAS-Araki-Alcock which passed closer to Earth than any other observed comet over the past 200 years (5 million km in May of 1983).

The highlight of May was the Eta Aquariids. Similar to the Orionids of October, the Eta Aquariids are produced by Comet Halley. This year’s display was hampered by a bright early morning Moon but still produced healthy numbers during the last hour or 2 of each early May night.
