Are you asking for a more detailed explanation as to what happened with
the cart change darks?
The darks usually start integrating within a few seconds of the command
being issued, but no exposures were integrating after 20-25s so Dan
reissued the command and the log said the dark script was already running
and we saw them start just fine albeit after considerable delay. The chart
change darks delay happened once again after that last night. No sky time
was lost.
