The Occultation of a R=12.0 Star by Asteroid 1995XT

From Santa Cruz, at 9:51:53pm for 7.6s

OWcloud path

This is a very good event. Long, 7.6s and deep, at 60 deg alt in Az 175 almost due south, high up in Leo. It will permit accurate shape analysis of this still un-named (unstudied?) asteroid. The rank is high and the path goes level across downtown Santa Cruz and Cabrillo College. I will likely be trying it from Cabrillo College after my evening class.

Karl, you are north of the path. You'll have to get south, I'd suggest at Castelegno's, to get it. Olive Springs isn't far enough for high odds.

Karl did not try this one.

I observed from my Mill Street base-of-ranch-road spot, and saw a 7.12s event. 4x setting. Excellent data light curves.

"Looks like a miss for monday night's 1995 XT, 2x from home. I tried TME and a 12 stack of static apertures but don't see a hint of an event. I did a detectability test and it said .2 sec or longer would be detectable, and this was a long 7.59 max event. Curious because I wasn't far from the center line.  Will be interesting to see what you got."
