Leonid Meteor Shower This Weekend
Graze on over to the International Meteor Organization's October to December 2006 page and skip down a bit:This year may bring a return to still higher Leonid activity, perhaps with ZHRs of 100—150. The timing above (Maximum: November 17, 20h50m UT [Fri 17 Nov, 2:50 PM CST]) is for the nodal crossing, and if recent past years are a guide, any associated activity near then may be swamped by other filaments within the stream. The prediction of higher (though not storm!) rates from the 1933 filament by Rob McNaught and David Asher is timed for November 19, 4h45m UT [Sat 18 Nov, 10:45 PM CST].
Here's where the radiant will be -- in the head of Leo, which looks like a large backwards question mark; click on image for full-size (640 × 480) map:
At my latitude (~40° N), the radiant will be rising in the east-northeast around 11 PM CST. If the prediction quoted by the IMO holds up, the first hour or two of Saturday night's portion of the shower may be spectacular for observers in the eastern half of North America.
(Previous mentions of the Leonid shower on Arcturus occur in the unimaginatively-titled posts Leonid Observing Reports?, which recounts the brief but overwhelming meteor storm of '02, and Leonid Observing Report, from 2003.)
