Observing Summary:

Large clouds were on the horizon at sunset, but they soon cleared away.  Clear observing night, pretty good conditions.
When rotating the slit angle, the rotator angle suddenly went to numbers around -600 when I was rotating to +70 degrees.
After rotating all the way to +90, then back again, the problem fixed itself.  Other than that, no problems were encountered.
