Morning:
Delayed some activities a bit this morning, so we could attempt monitoring of SR3 for glitches while in DRMI. From about 7:55 - 8:35 I went through an alignment (since there was no DRMI locking over the night, & Richard wanted it ). After the alignment, waited for DRMI to lock, but no luck; so started to allow planned Maintenance Activities as planned (see log below).
Afternoon:
All of the activities lined up for Maintenance were mostly completed (an item or two were not attempted). So around 2pm is when we transitioned from Maintenance to Alignment (and then Locking).

Locking was not trivial since there were several issues which came up (polarization was bad for ALSY, and we had to adjust this in the MSR)
-
VCO was also railed for both arms!
-
2:30-ish: It was discovered that trend data was corruped after CDS work earlier in the day. CDS team was able to restore things eventually (this did give some Guardian errors [for a while] due to nds data not being available)
-
2:45-ish: Ended the afternoon locking DRMI with Kiwamu (Re-locking Team Member for night). Have tried a few on-the-fly alignment tweaks. Kiwamu is looking for other issues as well. Handed off to Cheryl.
