Science!
---=== OBSERVING SUMMARY ===---
Spectroscopy and wind.  The sky was clear all night, but high winds kept us
closed for a few hours.
Finished Cartridge 3, plate 2550, segue148 with 1X20-minute exposure.
Finished Cartridge 9, plate 2137, chunk109 with 1X20, 1X10, and 1X15-minute
exposures.
Got good signal on Cartridge 5, plate 2162, chunk112 with 1X15 and 1X25-minute
exposures.
Misc. Watcher errors in the Problems section.
---=== OBSERVING LOG ===---
Afternoon:
---------
The telescope has been checked and prepared for observations and all systems
are functioning properly.
There is an alarm (red blinks and bipping) on circulation panel, probably the
settings of block has to be adjusted to warm outside temperature.  We need
help to do it.
The collimation is set for 5.5C using median mechSend temperature.
00:30Z - Began ventilation. Doors and louvers open, fans on.
Night:
-----
01:37Z - Enclosure off.  Opened to clear skies, but high wind and poor seeing.
02:40Z - Cartridge 1, plate 2409, seguefaint134.
Needed an FK5 to acquire the field because of sky brightness (we started a
little bit early to get the focus and offsets all set to go).
Pre-calib.
