H1 Morning Status: Struggles Locking DRMI

H1 was down over night, so the first action was to run an alignment of H1.  Unfortunately, there was an earthquake when alignment was started.

Alignment Notes:

Currently have made it up to DRMI and have decent looking flashes and have even had short locks, but they are only lasting ~3 seconds.

SRC Alignment still has issues at ACQUIRE SRY, but this time it stated the reminder about aligning by hand, so will attempt that.

Misaligned SR2 was the issue!  (and this time, the ALIGN_IFO gave the reminder about Aligning SR2.  At any rate, DRMI locked up on next attempt. 

Ibrahim is here now, and he touched up PRM and SRM to get our POP18 & POP90 better at the DRMI_LOCKED_CHECK_ASC state.  We then had a lockloss at PREP ASC though.  Now repeating on next attempt.
