On tap for tonight, as for last night, was to finish the collimation tests that
were tried for previously, and to try for on- and off-equatorial scanning.
At 1900 we had scattered clouds and humidity at 70%, with a storm cell off by
Las Cruces moving E (i.e. toward the Observatory).  The forecast was not
good for this evening.
The telescope was operational with the counterweights set to a
voltage of 690.
The mosaic camera was cooled in anticipation of obtaining data, starting
at about 1800 MDT, in the hope that the cloud-cover would dissipate.
Connie worked on the mosaic camera for most of the night.
At 2000 MDT we had lightening over and all around us, and violent rain/hail/
lightening starting from about 2100 until 0200.  From that time on, the
rain was far less violent, but still continued.  At 0330, the humidity
was 111%!.
We called it a night at 0400 MDT.
Jeffrey for the lot...
