J. Kissel, E. Merilh, J. Driggers, K. Izumi, D. Barker Just on an update on the recovery process this morning: - ~12:30 UTC Giant EQ in Alaska (LHO aLOG 35930) - EQ is on our tectonic plate, so happens too fast for Bartlett to switch ISI Systems to Robust / EQ mode, so they all trip - ~14:30 UTC Giant Aftershock (LHO aLOG 35931) - Same story: EQ is on our tectonic plate, so happens too fast for Bartlett to switch ISI Systems to Robust / EQ mode, so they all trip - ~15:00 UTC Ed Merilh takes over from Bartlett - 16:30 UTC Ed having trouble with INITIAL ALIGNMENT (specifically with PRC WFS loops would not close) - Solution was to skip to MICH_DARK_LOCKED and make sure BS was well aligned, and then back to PRC and move PRM in pitch until AS port looked well - ~17:30 UTC Finished with Initial Alignment, microseism and EQ band have sufficiently rung down to begin locking - ~18:00 UTC Found that we couldn't get past LOCKING ALS because ETMY Bounce Mode, spent a LONG time running with ALS_DIFF at a factor of 10 less gain, and SLLOOOOWWWWLYY damping the mode with gains of 0.001, and we eventually got up to 0.028, and then - ~20:05 UTC The SEI BS crashed. Since we're already down, we voted for just completing all corner station and end station front-end reboots. Dave's working on that now, more news on everything later.
