OPS Day Midshift Update

IFO is still down and attempting to lock.

After one initial alignment, with a manual SRC and ALS (X) locking, IFO failed at main alignment during ALS locking again. This got the attention of Sheila, Jenne and TJ. After a lot of moving, the issues were found to be related to the normalization of the X transmission signals. We renormalized the signals and finally locked ALS successfully for the first time today.

Additionally, an EQ in the Norweigan sea took us down (after DRMI locked).

As of now, DRMI is locked, the Earthquake is passed and we are (hopefully) headed for NLN.
