              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with some clouds that were thick and a little difficult to punch through. However, they cleared up nicely after a few hours and we had clear skies and good seeing for the rest of hte night.
Echelle pressure was at 6.144e-5 torr when I closed up.
No problems tonight.
