              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We opened around 02:30 with clouds. It was about the best sky we had seen for the whole night.  We could just barely see the observers target and with no radar returns I let him observe. Clouds grew worse by 03:30 and he went to a brighter backup target (Jupiter).  When we couldn't even see that, and inspecting the satellite images, we decided conditions were only going to grow worse and gave up for the night.
I thawed the Echelle level gauge this morning.  It is working once again.
