(* means a trouble report has been issued or appended to)
The telescope was not opened this evening due to high dust counts, overcast
skies, and lightning.
Jeff Morgan and I did some testing on the Guider in the middle of the evening.
He seemed to be pleased with the results, but we could not open to continue
the tests.
