Using the lockloss select tool, I saw that ASC-SRC2_Y seemed to step out a bit further than usual, ASC_AS_C feeds into SRC2_Y and it's read at OM1 from our Optical Sensor Layout (DCC G1601619). OM1 appears to show some abnormal motion seconds before the lockloss? But trending back further, this behavior shows up in the 2 previous locklosses (16:35UTC, 09:07UTC) too althought not as strongly, so maybe it's just another witness?
