The Occultation of a W=10.9 Star by (26439) 2000 AZ1

This is a low rank event, but bright and easy and the centerline is not far away. The duration is only 0.4s, but for such a bright star, this will be easy to see on your external monitors. The odds on the centerline are 42%, and 40% for my site at the top of Rodeo Gulch Rd. For Karl, odds are only 12%; they're 36% on the blue limit lines

Alt=72, Az=174. The field will be rotating significantly as you try to find the target, so be wary of not having perfect angle on the field. The target is ~due south during the event. You may be able to tilt the tripod a bit and still get away with the usual configuration. That's what I will do. And be sure to shove the telescope ALL the way forward in the fork, to allow this.

 

   

 

Results:

We all 3 tried this, in newly cleared skies after the rain earlier in the day. I tried from the top of Rodeo Gulch at the east side overlook. Kirk from the Eco Preserve in Bonny Doon, and Karl from home. Bright star easy to see, and a definite miss for all.

The star was quite bright, overhead in a dark sky, and I followed it easily on the monitor. No dimming seen. A miss, it seems. I observed from home, at the base of my stairs, at 2x setting. Very nice tight data under clear skies. A clear miss.

Looks like a miss for 2000 AZ1, no sign of an event.
2x at the BD eco reserve.
