Oct 9/10/11/12 Meteors

The “meteor” sky is starting to get busy. There are at least 6 showers producing activity at this time. Though most of these showers are minor, a few (like the two Taurid streams and the Orionids) are producing multiple video meteors per night.

The table below summarizes results from the past 3 nights. The first 2 nights were hampered by persistent cirrus which suppressed meteor rates. The last night was mostly clear though rates should have been higher. As it turned out, I had one of the parameters for the MetRec detection code set wrong. This probably cost me 10-20% of last night’s meteors.

Since the last meteor summary, 2 additional showers have become active. For more on these showers (the Zeta Taurids and the October Ursa Majorids), see Bob Lunsford’s Meteor Activity Outlook for this week.
