This morning, while waiting for Maintenance, noticed that after the In-Lock SUS Measurement, we did not "automatically" return to Observing (which would only be a few min due imminent Maintenance).  Turns out there was an ITMx SDF Diff for (H1:SUS-ITMX_L3_LOCK_L_TRAMP, see attached). 

Since it was starting to get hectic in here leading up to Maintenance, I did not do anything about this SDF and kept H1 out of Observing.
