The Occultation of an 11.4 Star by Asteroid 2000-JD31

This is a bright occultation, and should be easy to find by just doing a GoTo the open star cluster NGC 6469, about 2 degrees above the nebula M22. However, the path has a wide uncertainty. It's about the same track whether we observe from the Carrizo campsite, or Atascadero. Vince Sempronio is also going to try it, from Sierra Vista, AZ on the centerline. So, our station south of the path will give a complementary site. The odds of a hit, for both of us, is only 17% however.

 

   

 

Results:

Kirk and I drove to Carrizo Plain to get this one, and also Astrid a few hours later. We both got successful recordings of both events. However, the 2000-JD31 event gave us both a miss. We set up camp at our usual Astro campsite, then I drove back down to Simmler Rd at the intersection with Soda Lake Rd and set up my station.

Richard Nolthenius - IOTA report of this miss submitted 6/27/23

I recorded the data from the intersection of Simmler Road and Soda Lake Rd, in calm conditions, no clouds, but seeing was not great. Lots of scintillation. I watched carefully and despite scintillation, at no integration did the star vanish from the LCD screen. It should have been a full drop for an occultation.

Kirk recorded from our campsite, had a clear miss as well.
