May 1-10 Meteors

The end of last month experienced the peak of the major Lyrid meteor shower. The first week or so of May is seeing some signifiant activity from the Eta Aquariids (ETA). The ETAs are actually debris from Comet Halley. They are the sister shower to October’s Orionids (ORI). So if you’ve been seeing some long bright meteors during your early morning walks the past few mornings, you’ve actually been seeing small pieces of Halley’s comet.

The IMO Live ZHR page¬†presents reports from visual observers from all around the world. They have been observing a good shower with ZHRs of ~50. It’s too bad the radiant is only observable for an hour or so prior to sunup from the the NH.

The ETAs were predicted to peak around May 7 UT and the IMO reports confirm this. My meteor camera totals disagree as the number of ETAs has continued to climb even though we are 2-3 days past the peak. Perhaps the number of bright ETAs (which are the only ones my camera can detect) are still increasing even though the total number of meteors (bright and faint) peaked a few nights ago. Regardless, the ETAs should wind down from here on out.
