The Occultation of a R=13.7 Star by 2001VZ105

This is a very tough event for the 8SE. Only lasts 0.3s so no chance for long integrations. Should be doable with the 14" planetwave on the big observatory scope, however. Alt=28, Az=172 in Ophiuchus. The path misses north of MIRA but not by much. Nominal prediction is high, so odds are low-ish.

I observed with the 8SE in the lee side of the lightening cage at the foot of the fire lookout on Chews Ridge. I thought my data would be unusable, but on playback even with the wind, I could follow the star on the PyMovie reduction. Still, I was at 8x and the preducted duration was only 0.3 seconds so 8x means 8/50 seconds per integration or about 1/6th second. So that's only 2 integrations for a maximum occultation. The PyMovie light curve does not show such an event, and in any case the noise was too high to be able to conclude much, but a likely miss.

Kirk observed on the 14" Planewave. Looks like a miss, at 2x?
