                             (MJD 51636)
OBSERVING TEAM:
===============
Scot Kleinman (APO)  Shift 1
Atsuko Nitta Kleinman (APO) Shift 1
Jeffrey Hayes (APO) Shift 2
Ellyne Kinney (APO) Shift 2
Bing Chen (JHU) PT
VISITORS:
=========
Larry Carey (UW)
Steve Kent (FNAL)
Richard Kron (UC)
THE PLAN:
=========
If it clears, spectro unless photometric, then imaging.
SYNOPSIS FOR NIGHT:
===================
The weather was quite bad the entire night -- clouds, high humidity, wind and
snow.
TELESCOPE STATUS:
=================
Imager on telescope.
DIMM:
-----
INTERLOCKS:
===========
None bypassed.
SOFTWARE USED:
==============
IOP/SOP: v3_12_5
Watcher: v2_8_2
MCP: v4_1_2
WEATHER SYNOPSIS (see below for hourly data):
=============================================
Snowing and cloudy in afternoon with a giant sucker hole opening up
around 17:00.  The hole closed up by 20:00 and the weather stayed bad
for the rest of the night.  Even when the clouds cleared out, there was
either too much humidity or ice around to open.
GENERAL COMMENTS (see Problems below for details):
==================================================
As Steve Kent did not find any evidence for the light leaks, so we need not
persue this avenue.  The weather opened up at about 03:20 at zenith, but
all around at about an ALT=45 deg, there was cloud.  They came back in
by 04:00 and essentially never left.
We left the tapes from tonight in the drives, and ran "endNight" so that
the tracking s/w files would be copied into the right places.
"endNight" ran successfully.
