              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Taks completed:
- Arctic quad recovery
- Zero NA2 rotator: -0.0565
- spot check pointing:
echelle was good. Arctic was off by as much as 20 - 30" as we slewed around the sky.
Apollo was good. Since the pointing was not good with NA2, Russet was not able to track satellites, though she tried.
- New 1.25" KOSMOS masks
They look good! Widths are 1.25" and there isn't much in the way of burrs. The screws do show up as rather large black spots which could be an issue for horizon tracking.
- DIS contamination exposures collected
I feel like this came up before, but I couldn't log into DIS-icc from ObsA, I had to ssh into Obs1 and then into dis-icc.
