              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Task complete
- restart tron trunk
- restart tcc
- restart axis controllers
- zero rotators (-0.065 for NA2)
- Exercise M2 (maybe?)
- Test Kosmos MOS
More details in the engineering email but either shortly before or when restarting the tcc, the secondary mirror spontaneously power cycled and the mirror was listed as NotHomed. We were able to recover it and had no other issues with M2 tonight. Pointing was good and we were able to switch to different ports and instruments without issue (not sure if that counts as "exercising" M2).
We started the night out with clear skies but clouds rolled in at 3am and stayed until near dawn. However, we were able to get exposures with KOSMOS MOS! And Jupiter with the 0.66 High ND2 slit!
