                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Started cooling and opened the enclosure around 19:00.
 The Echelle guider locked up around 20:51 (stopped taking images).  The
 observer noticed it wouldn't change to a large field when she moved to
 her next target.  A reboot of the computer quickly fixed the problem.
 The humidity closed us down around 01:00 and we remained closed for the
 remainder of the night.
