# Unbiased, unpowered.  
# But left PAN and MOP up after confirmation from Dick Joyce that this was reasonable.

# Clouds overhead

# Ran 11 junk frames to clear out detector.
# Oops, was running with J filter instead of OPAQUE.
# Switched after 7 frames. 
# Re-ran new set of 11 frames.

# In general the successful focus values have been between 9000-9100 these few nights
# OA reported that her guide probe is somewhat defocused when WHIRC is in focus.
# Such that adding +100-200 to WHIRC gets the guide probe in focus.

# Realized that NOAO Science Archive grabs images as soon as they are taken.  So there's no point in overwriting files; it will just lead to duplicate file names when they're extracted at the other end.  Should just keep everything.

Shut down WHIRC a couple of hours ago.
