              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Huehnerhoff
New slitmasks created for all standard DIS slits and Echelle slitviewer.
Echelle interorder light measured to be 14.0.
Serious TSPEC slitviewer problem at start of night.  While creating new
slitviewer mask it was noticed that the slit was rotated off position.
After driving slit wheel through all slits the new slit position was even
further off position.  Call to B.Ketzeback and M.Nelson for help with
temporary solution;  see PR1283.
Intermittent light cloud cover till around midnight when thickening clouds
and incoming radar caused us to close.  Reopened for a short while until
more clouds and fast moving radar caused closure for the night.
