The Occultation of a 13.1 by the Asteroid Gyptis

Mar 12, 2022 at 7:56:46pm

 

This high rank event has a northern limit through the Santa Cruz mtns. Kirk, Karl and I are all inside the northern limit and have good odds of a hit. The event lasts up to 8.7 seconds, and is at high altitude of 62 degrees in the SSW. The hardest aspect is the dip in brightness is only 0.4 magnitude, so we should use maximum integration consistent with not getting too much skylight. The sun is at -10 degrees so that's another problem. Must get on this very soon after a successful 2-star align.

 

   

 

Results:

The C2A star field unfortunately had some bad data, and key stars needed for good pointing ID were missing or wrong. That's the backdrop for our sad results:

Richard Nolthenius
So, I never did ID the field. Even at high magnification in the LCD field I could not find a matching star pattern.

Kirk Bender
Kirk did ID the field, but had trouble with assembling the Optical train in time, as the -10 sun altitude cramped the time available to 2-star align and get our attempt on schedule.

Karl von Ahnen
Karl too was unable to ID the field. 3 strikes and we're out.
