Observing Specialist: C.Gray
gcam needed a read start during checkout but other than that things went great!! Or, ya know, way better than anyone was expecting. It was raining and storming all afternoon (with fog thrown in for fun) and UW01 logged in expecting to immediately return to their Saturday party only to find the weather was clear! We had good to moderate seeing all night.  CU07 presented us with the most GLORIOUS galaxy eye candy I've ever seen!  I wish they had been on a little longer :( JH01 almost made it to twilight but, in the end, the radar got us and we had to close at 4:14.  While it never rained, there was some good virga.
