alpha Aur unusual meteor shower tommorrow monring 9-1 5:33 am MDT
With respect to the Perseids, there was a discussion on this list about the how the ZHR rate changes with the altitude of the radiant above the horzion. One of the reference pages ( http://aurigid.seti.org/ ) includes an applet - the Ames "FLUXOMETER" - about mid-webpage that predicts the shower rate for western U.S. cities. Salt Lake is showing about a rate of about 30 meteors at 2:30 am and 50 meteors per hour at 5:30am. 30 p/h is about what the Perseids a few weeks ago. There is some uncertainty to predicting the peak. The FWHM period is 25 minutes around 5:36 MDT but the shower may last longer. Vaubaillon is recommending watching an hour around the predicated peak. Because of approaching sunrise at our location, Utah is limited to the 4:30 am to 5:30 am tail. - Kurt _______________________________________________ Sent via CSolutions - http://www.csolutions.net
