Having trouble getting past PRMI and DRMI, and the X and Y arms did not look that good. Run Initial Alignment. The alignment was having trouble getting PRM to converge. Tweaked up the PRM alignment, and completed Initial Alignment. After a couple of tries locked at DC_READOUT. Turn over to Evan for commissioning. Go up to high power; Shelia and Evan commissioning. Second half of shift mostly spent trying to relock. Damping Roll and Bounce modes that were ringing up. Also had issues with the ISS Autolock oscillating and the FSS PZT MON saturating. At the end of the shift a magnitude 6.9 EQ hit, bringing up the seismic to near 1.1um/s. Put on the SEI_CONFIG in EARTH_QUAKE_V2, but to no avail. Set the IFO to DOWN, and turning over to Patrick.
