- 16:34 UTC Lockloss
- 17:40 UTC We held in PRMI_LOCKED and tried to increase the buildups by adjusting some optics
- Then we tried to go up bypassing ASC, by manualing around the states. I lost it at TRANSITION_TO_3F
- I'm trying to do the same in DRMI_1F, adjust optics by hand, but its keeps killing it
- 18:55 UTC We tried running the dark_offsets script
- 20:41 UTC EQ mode, from near the Galapagos islands
- 21:12 UTC Observing after accepting SDF diffs
- 00:20 UTC lockloss , there was a motion spike in the 0.3 - 1.0 Hz bandwith
