Their run went OK, except for some problems with the configuration of their Macintosh. Nancy Levenson and Ravi Sankrit were onsite to observe for JH03. Their run went very smoothly. The sky was photometric and the seeing was sub-arcsecond (at least in the IR). They lost one exposure due to the altitude axis pointing being about 11 arcmin off. The magnesensor error showed this and it was quickly corrected. 2nd half observing specialist: Karen Gloria The second half observer was Matt Holman for NM07. He had a lot of network trouble, which may have been at his end at the CFA. His connection was so unreliable we decided it would be better if I did the observations. This solution worked reasonably well, as his program was quite straightforward. Although the sky was clear, the seeing was not as good as it had been the first half of the night. We were averaging 1.5 - 2.0 arcsec much of the time. OBSERVER COMMENTS NM07 (Holman): I had network problems, but Karen was able to carry on the observing.
