              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Given the forecast, there wasn't much hope for the night, so I was pleasantly surprised when we were able to not only be open for A half but actually get some data! Not good data. But there was continuum. Now, B half...yeah, we couldn't even get much on a 3rd magnitude star. Given the high winds (gusting to 36 mph), the thick cloud cover (which was only expected to get worse), and the fact NM04 needed 2 hours of clear skies, we called it a little before 3 am.
No problems tonight.
