                  ------------- ACTIVITY LOG --------------
 Observing Specialist: Noel Camron Hastings
 Opening was delayed due to high winds, clouds and such. The clouds
 finally dispersed around 01:00 and we were able to open with high
 winds just under the limit. Smoke was noticed much of the night, but
 none of us sure which fire or state it was from. Seeing was not too
 good and air was turbulent. As the night progressed the seeing
 improved and the skies cleared up. We did have a couple of grim
 failures, the standard 'type 1' failures as well as one instance of
 the Grim ICC disconnecting from the hub. No lost time, restarts
 fixed it within in a minute.
