The IFO timed out during initial alignment because ALS Y would not lock. Flashes were at 0.8 but it wouldn't catch. I tried to manually move ETMY, TMSY, and eventually ITMY, but I couldn't increase the height of the flashes. After about 30 min of fussing with it, it caught and stayed locked. I have no idea what was different though.
Initial alignment has just finished and main locking has commenced.
