                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I opened the enclosure and started cooling around 16:00.
 Seeing was fairly decent for most of the night with only a couple short
 (45 mins) durations where the seeing blew up to around 1.5 arc sec.  For
 a quite a while we were around 0.7 to 0.9 arc sec.
 When the 2nd half observer started around 04:10 the seeing with the
 Echelle was 0.83 arc sec.
 No problems to report tonight.
