              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear. We had an issue with echelle, where as it was warming it gave a bad image during checkout, which led to my believing it would not be usuable for shift. A subsequent image taken after sunset showed it had cooled enough and was working. We scrambled and got NM01's observer back online, with minimal time lost.  Weather was clear, but seeing was a little below average.
