From: Joseph Assmus, San Diego, California Date: Fri, 17 Nov 2000 10:13:01 GMT brrrr.. it was cold.. greetings all. Just got back home from the local mountains of San Diego. At the last minute, my crazy Dutch neighbor, Arjen and I drove up to the Laguna Mountains to observe the Leonids. Bob Lunsford met up with us 30 minutes after we arrived. My intention for the night was for a short casual fun session with no formal data collection. The skies were absolutely crystal clear.. but it was cold (low40s F) and there was a blistering northern wind the whole time which probably put the "feel like" temp down to the 20s F. Using star count area #8 in Taurus, my LM was 6.1 (even with the moon on the eastern horizon. I observed for 2 hours 0630-0830 UT (due to work considerations) and counted a total 25 meteors. Time Lm Leo Tau Spo 0630-0730 6.1 4 1 4 0730-0830 6.1 12 1 3 Because the radiant was so low, most all the LEOs were nice longish grazers.. the longest being ~90-100 deg, no fireballs. One -2, One -1 and the balance 0,1,2. (I collected no magnitude data tonite, though tomorrow, I will). All SPOs were quite dim (between mag 3 and 5) Its 2:03am (pacific time now).. Im going to bed. Bob is still up there observing (and shivering) as I type this. I look forward to hearing how the rest of the night turned out. We are expecting pristine clear skies again tomorrow and since its a Friday night, I will observe all night and collect formal observations for submission. --- Date: Sat, 18 Nov 2000 18:53:30 GMT Leonids November 17/18, 2000. Bob Lunsford and I observed a nice display from the Laguna Mountains in San Diego California. The air was cold (lo 30s F. the wind was not nearly as bad as the previous night). The sky was clear all night. Some of the highlights: - several beautiful Leonid earth grazers with path lengths well over 80-90deg - An awesome -2 Leonid with that familiar *intense* turquois-blue shade. For me, this these are partly what makes staying up all night worth it! - A beautiful -2 Taurid with an absolutely pure orange hue - The -3 and -4 Leonids I did see were on the edge of my visual field Visual results obtained by Joseph Assmus Lat: 32deg 49' 49" N Lon: 116deg 29' 43" W I faced East (azimuth 70deg) for the first 3 intervals, the turned around and faced West (azimuth 70deg) forthe remainder of the night.

Bob traditionally sees more meteors than I do, however, I turned to face west before he did and it seemed like for that period I was seeing both more LEOs and SPOs than he. Well, thats enough data crunching and typing. its 1100am, (bedtime-finally!)
