              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
I made new masks for the dis slit viewer. There were clouds over us that cleared enough during sunset that we could open for a little bit before the humidity exploded into fog. But the laser fired! YAY!!!! PEW PEW PEW!!! And no one got anything after that. The humidity was a roller coaster all night and then there were radar pings around us. WY03 couldn't use time after 4:15am, which is when I called it quits.
