Re: (meteorobs) Re: quads on the 3rd not 4th
For 2001, the IMO's first activity profile (the only one I can find on the web) shows a maximum at 13:30UT (apparently a bit late). About six hours before, at 7:40UT, the ZHR was 56. This was admittedly based on a small sample of 5 observers and 98 meteors, and the same table shows a ZHR of just 17 at 5:10 UT. If more observations were submitted afterwards, I'll bet it smoothed out the ZHR curve. But yes, it would be worth watching if you can get a halfway decent LM despite the Moon.
Aside from a couple of "uncountable" periods of partial clearing on December 14th and 22nd (at least the dates were right), there hasn't been much opportunity to look at the sky in So-Central Oregon recently.
