From: Dustin Brown, Vancouver, WA Date: Fri, 17 Nov 2000 13:10:50 -0800 I enjoyed the brighter 11/16-17 Leonids despite the moon. For 11/17-18 I will travel to the Columbia River Gorge to hopefully get to a LM of 5 or better. The Pacific NW is actually clear for November Leonids ! Anyone in Portland Oregon going to the Rose City Astronomers Leonid star party tonight (Friday) at Rooster Rock in the Gorge ? (You can E-mail me directly so as to save on cluttering the meteorobs list traffic during this busy time.) ................................................................................

Since the LM wasn't up to 5, I think I will travel to a "dark" site for the 11/17-18 observation. Due to the moon I can probably only gain a 0.5 improvement in LM but at least that would get me up to 5. (A web page program I found calculated that at 30 degrees from the quarter moon the best magnitude possible will be about 5.5 We will see.) ---------------------------------------------------------------------------
