Seeing was perhaps the best I have experienced so far here, being from 0.6 to 1.0 arcsecond throughout the first half on both the instrument and guider. Some small puffy clouds passed through moving very fast around 22:00, but did not go through the science field or seem to affect the seeing during their passing. Second Half Observing Specialist: R. McMillan Another quiet night of photometric skies and stable, subarcsecond seeing. There was just a bit of excitement at the beginning of second half when the observer got a segmentation fault in response to a filter move command. He restarted spicam and got a different error, I tried and had no trouble, so he logged out and logged in again, and that fixed the trouble. After that, everything settled down to continuing our streak of mind-numbing perfection.
