              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Humidity kept us closed at the start of the night.
Bad NICFPS image at 04:46 (Black/White bars), 'nicfps expose init' fixed problem.
Echelle slit images dramatically dimmed for some reason, see echelle slit images 1461 - 1474 ( changed to an ND1 filter during 1473) and then again 1476-1478.  No clouds were in the sky.  May be related to PR# 1307, although different symptoms.
This may be a cold weather related issue.  The mirror covers again refused to close remotely at the end of the night tonight.  This happened last night and I told Bill about it.  Looks like it happened again.  No power fluctuations tonight and they were working fine at the start of the night during checkout.  Cycling the switch fixed the problem.
