              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
gcam needed restart
dataq needed restart
The night started out with radar near by that was coming right towards us. And then, just as it got over us. Gone. The seeing wasn't the best when we opened but it really improved as the night come on! Humidity started going up toward the last two hours but it stayed below the limit and we were able to go the rest of the night.
