                ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Dembicky
I forgot to record the weather data for the first focus.  I tweaked it
during the first half.
01:50 slitview camera stopped (locked up?).  Luckily the telescope tracked
well enough that when I noticed the problem several minutes later the star
was still on the slit.  Restart of ecamera and ecam fixed the problem.
