Observing Summary:

Clear weather. Sub-arcsecond seeing.

Even though the MIS panel indicated that all lamps were off, 
the Xenon lamp was on during two of our science exposures.  
This might be the result of clicking the  lamp off  button
while the  finder mirror  was moving.  Even the FITS headers of 
the exposures indicated that the lamp was off, even though it was
actually on.
