Good morning!
There was no guarantee that host2 would be up at the end of the night, so
I just wrote the log as a text file.

                      OBSERVING LOG
                 Wednesday December  9, 2009
                       (MJD 55175)
---=== OBSERVING TEAM ===---
Alaina Shelden
Dmitry Bizyaev
Afternoon:
Steph Snedden
Kaike Pan
---=== OBSERVING PLAN ===---
        Keep generator running!
        Monitor the spectro CCD temps.
        Stay warm!
---=== OBSERVING SUMMARY ===---
Sky was clear, but we stayed closed because we don't trust the generator.
The computers were powered down, except for host2.
The imager was left on the telescope, and we left it pumping.
---=== OBSERVING LOG ===---
Afternoon:
--------------
00:19Z   We've been educated in how to restart the generator, how to check
spectro
                                  temps, and how to shut off the imager
pump.  We're leaving it on the telescope and pumping, unless the generator
goes down for more than about 20 minutes--then we'll shut it off.
Internet was down from almost exactly 07:00Z to 08:00Z.
Dmitry is waiting for Dan Long this morning (we switched off halfway
through the night).
Night:
---------
01:45Z   Power is still running happily.  Spectro temps are still happy.
03:08Z   Spectro temps good, power still on (flickering a little, but
still on)
03:57Z   Spectro temps good.  No power problems.
04:55Z   Spectro temps good. Power good.
05:50Z   Spectro temps good. Power good.
06:50Z   Spectro temps good. Power good.
07:03Z   Internet stopped working.
12:12Z   Continued checking the temps every half-hour: they never changed.
 The internet went down from 07:00Z to 08:00Z, when a technician called us
to say it was up and running again.  Dmitry is waiting for Dan Long to get
in this morning.
---=== TELESCOPE STATUS ===---
