NICFPS was not happy tonight
2019-01-29 23:39:26 APO.APO-Jack 30 nicfps w UNPARSEDTEXT="Clearing H1RG serial registers Error: 0x455252"
2019-01-29 23:39:26 APO.APO-Jack 30 nicfps w WINDOW=UNKNOWN
2019-01-29 23:39:26 APO.APO-Jack 30 nicfps f UNPARSEDTEXT="\"Setting WINDOW FAILED!\""
I issued a 'nicfps expose init' command twice and this cleared the problem.
Clouds and possible precipitation kept us closed until around 21:30 tonight.
I saw an example of a bad slitviewer shutter with the echelle slitviewer (see images 6 and 7).  We saw more examples of this in later images as well (10-12).
We closed at 01:07 due to increasing clouds, not that we hadn't been fighting them for a while at this point, but now we had radar returns in the NW part of the county.
