               ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Noel Camron Hastings
 I opened the dome at 17:35 to cool even though the heavy cirrus was
 not promising. No problems encountered and we tried to take data
 through the cirrus with about 10% transmission decreasing to 3%. We
 closed at 21:50 MST.
 2nd Half Observing Specialist: Jack Dembicky
 Continued clouds all night with no chance to open.
