              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Clouds, clouds, clouds. Wind, clouds, rain.
We opened on time but barely glimpsed Mercury before he hid behind the clouds. UW01 tried their best to see some stars, but they were thwarted shortly after their program started by sudden forming rain and we closed at 21:12.  DD01 never had a chance.  Their objects were faint and the clouds, rain, and wind wouldn't let up.  They called it near 5am.
No problems tonight
