              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The echelle IOL script failed during checkout and I found that problem was due to the filter being set to Blue. I set it to open and ran the script again and it was fine. The weather, however, was not.  We had some pretty good storms all night with lots of nearby lightning that caused a few flickers (but not any power outages). I thought for sure things would clear up by 4:30 but the clouds just kept forming over us and we were never able to open :(
I would like to note that I had the worst moth scum on the alt drive that I've ever experienced.  It was at least 3 moths (??!!) and it took multiple assists (pulling up on the ladder) to walk our fair lady far enough to scrub out the guts.  IT STREAKED THE FULL ALT RANGE!!! I *think* I got it all off but I wouldn't be surprised if I had issues with test slews tomorrow.
