Once unlocked I reloaded ALS_Diff to load in TJ's Changes from earlier today.
Guardian gave us an ALS_DIFF Error after reload of ALS_DIFF:
Camilla and I checked the log and subsequently line 240

We made some changes to ALS_DIFF after ALS_DIFF to see if it we could fix it.

We didn't get much further than the error  before we got a lock loss that did not take the IFO to down. It took us back down to AQUIRE_DRMI_1F but stayed locked for a few moments then eventually got a lock loss that took us to down.

Accepted some SDF changes for H1:ASC-DSOFT_Y_GAIN & H1:ASC-CSOFT_P_GAIN.  Screenshot included.

PI Mode 24 Rung up and Vicky and I manually stepped through some phase shifts to damp it down.
It then continued to ring it's self up for the next 40 minutes.
