              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Kosmos seemed like it took an extra long time to fill this afternoon.  Tank 9 was used.  Mark last filled it at 05:30 and I filled it at 19:15.
I delayed opening a few minutes due to nearby rain clouds to our west.
I closed again at 00:20 due to an approaching storm to our SW.  Rain started at 02:45.
I started the ARCTIC quad recovery at 04:00.  Quad recovered and 400 biases started.  setpoint back to 182K and ramp set back to 0.1K/min.
Kosmos seemed to fill more normal, although NICFPS filled faster.  Maybe tank 9 is just s slow fill.  I will see this afternoon.
