- After the demod board was fixed, we could not transition to DRMI 3f. Stefan found that there was no 3f signal to transition to. He and Richard went out and disconnected/reconnected cables and it came back.
- Evan changed something in the ALS guardian code that had to be fixed.
- There was a 6.4 earthquake in Chile.
- I ran through an initial alignment near the beginning of the shift.
- Sheila told me that although there is less sensitivity to alignment in locking PRMI, there is currently something not quite right about the PRMI acquisition and we have a better chance of acquiring DRMI than PRMI now.
- I tried to go from PRMI to DRMI, but guardian would not let me. Sheila said she has fixed this now.
- We made it to NLN at 22:56 UTC.
