              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Rain in the afternoon, clouds that were starting to turn into fog at sunset, loads of humidity, rain that turned to ice yet more humdity, some close lightning strikes, and +50mph winds.  The only thing that surprised me is that it didn't snow.
The group on site pretty much gave up on the night.  But wait, a ray of hope!  The humidity started dropping after 1am but the clouds were too low and too thick to see through. Wait, what's this?  Little patches started appearing near 3am!  But my poor trainees didn't think there would be enough time.  Alas, they had to leave site at 8am to catch their planes and they abandoned hope by 3:30.  There were 12 of them onsite so I didn't not list all their names in the nightlog.
I did not have a program that could fill the time (drat Venus for not being up) so I called it quits at 04:30am.
I took darks with Tspec all night. All corrupted :(  Other than that, no problems tonight aside from some very tired students (but they persevered and are now trained!).
