              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had clouds all night with radar returns and, worse, high pollen count (and boy, my eyes can feel that pollen!). Given the high pollen, there was no chance of opening tonight.
- Nicfps was down yesterday and, after rebooting the nicfps computer, I was able to get nicfps back reading exposures again.
- I could not access /export/arcsat from ObsA. I tried ssh-ing into tron and also couldn't reach arcsat. It was fine with Obs1 and 3.
- We were NOT able to run KOSMOS focus because we could not get on sky.
- Russet ran DIS contamination and we were both confused as to why the red counts were so low. Either though we both looked, each of us thought we read that the R300 grating was installed when, in reality, the R830 was installed, which would explain the lower counts.
