1st Half Observing Specialist: Karen Gloria
	The telescope was opened at 16:30.  Eric Deutsch observed a GRB field with
SPIcam, then generously gave some time (0.4 h) for lens monitoring.
Afterwards, he observed with DIS.
2nd Half Observing Specialist: Camron Hastings
	I took over with scattered high cirrus that soon became so thick that we
closed at 22:30. Eric took a set of lamp cals and flats and then said
'audios' for the night as it was getting late and there was no improvement
in sight. The clouds continued and as the last half of the evening was OPEN
time I decided to close shop early. No echelle work was done because of
clouds, and Craig also mentioned that the new echelle ICC and the new 'test'
MC were having problems and he would rather not have them run unless it was
really necessary. He said that he will clean them up Tuesday when he comes
in...
