              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Due to the tertiary not being able to be moved from NA1 to NA2 port tonight, we had a swap of programs for 2nd half.  NM10 will be taking the time orignailly assigned to BY03.  There was nobody at BYU that could use the echelle tonight.
DIS temps @19:40 196, 193
DIS temps @01:50 190,187
We finally were able to open at 01:50 once the clouds cleared enough and I felt it was safe to open.  We still had clouds around us but the precipitation threat seemed to be low.
No telescope problems tonight.  Clouds did return at around 04:45 but we finished obseervations with the echelle.
DIS temps @ 05:50 196, 185
