                  ------------- ACTIVITY LOG --------------
 Observing Specialist: Noel Camron Hastings
 We opened the dome at 18:56 MST to cool before beginning. Craig fixed
 some issues with the MC that led to last night's troubles. Tonight
 started smoothly and no problems were encountered with DIS II or Remark.
 Second half started under thick clouds. We remained open.
 Second half was punctuated with GRIM ICC crashes and subsequent restarts.
 Three to be exact.
