A great show, best I've ever seen by far...100's of meteors with the bulk between 0200 and 0330 (all times in PST). Starting in earnest around 0130, by 0415 when we finally bagged it for a few early morning ZZZ's, activity was still on the order of a 3-5/min, and showing little signs of slowing down.Peak activity seemed to be between 0200 and 0245, during which we counted 83 in a single ten minute period - equivalent to almost 500/hr. Activity was not constant, as some gaps had only a dozen or so meteors within 5-10 minute periods, while at other times during swarms ( I believe there were three "peaks"), multiple meteors were visible nearly simultaneously. Shortly after 0215, we estimated in one minute a max count of 19 (even with three sets of eyes, counting at times was impossible), which occurred quite suddenly after a brief lull. Active intervals usually lasted 5-15 minutes each, with "background" activity mostly in the 2-4 meteors/min range. While all the meteors had Leo generally as the radiant point, (we saw zero non-leonids meteors), they curiously seemed most numerous in three distinct areas of the sky away from Leo: slightly east of and including Orion; north of Ursa Major (big dipper); and the vicinity of Gemini. It was our observation that activity seemed to concentrate in one place or another, but rarely simultaneously. The largest meteors (although bright ones were periodically seen throughout our observing period) seemed most frequent after the peaks of swarms at 0230, 0300 and 0320, while generally small, fast meteors were seen during the swarms. Many, many meteors with residual tails of colored smoke were seen, mostly reds and blues, and a few greenish. Very few yellow trails. Preliminary data from SpaceWeather.com had the peak at 800+/hr in the continental US, and 1200/hr in Hawaii. Unconfirmed reports from a high elevation observatory in the Southwest (Arizona?) had peak rates as high as 2,220/hr, however many were reportedly very faint and were likely invisible to observers closer to sea level. Local news sources said NASA estimates over Cent Calif ranged to 1,200/hr.We observed the event from Sonora, in the Sierra foothills, elev 2,000', under crystal clear skies overhead and hazy horizons. Noted three fireballs that actually created shadows on the ground with 2 producing long-lived ion trails that lasted over 1 minute (both blue-green). Was lucky to get almost 4 dozen meteors on video-tape, with a couple particularly brilliant. 1 such meteor was captured flying right through Orion, and may be of good enough quality for a still. I found that by setting my video-cam to the Super Nightshot mode (which is the infra-red only setting), a couple of meteors not seen optically showed up via their heat trails. Very cool.
