This is a bright, easy event, with good rank and RUWE=0.85. Kirk and I are just outside the southern limit at home, and Karl is just outside the northern limit, at home. I'll be trying it from the vacant lot at TreeTop Lane in western Scotts Valley off Graham Hill Rd.
Alt=49, Az=94 in Gemini, just 3 degrees above/left of Jupiter

I got a positive, about 1/2 second, from TreeTop Lane off Graham Hill, in the middle of the vacant lot. At 1x setting. Kirk also had a positive, from "the Berm". Karl tried it; not sure the result yet.

Bernard's and my chords are almost on top of each other. Our data should add confirmation for unusual events. |
The 3-point drop just 1 diameter 1/2s before the actual event is curious. Was this a graze? Noise? A secondary moonlet? Kirk's chord wasn't far from mine, but his event was 3x longer than mine, suggesting a very oblong asteroid. It'll be interesting to see how it plots up. For now, I will not try to report the 3-integration drop as a separate event, but we'll see how it dovetails with Bernard's data, if he was successful.
I got a 1.2513s event for Assisi, 1x at the Berm, longer than the predicted max of 0.79s. There is a single point spike in the center of the event, I don't know if that's just noise.

Did not record this one, alas.
