Microseism is currently very high (moving between 0.73 and 0.93 um/s), and we have had threefive (we had two more locklosses while I was writing this) locklosses at different states (ALIGN_RECYCLING_MIRRORS, FIND_IR, ACQUIRE_DRMI_1F, ENGAGE_DRMI_ASC, FIND_IR) after running an initial alignment, so it's possible we won't be able to lock the detector for a bit due to the high microseism. I'll let it try a couple more times but we might have to wait for the ground to calm down. Luckily wind is low (10mph) and looks to be decreasing.

We almost made it up to NLN but lost lock at TRANSITION_FROM_ETMX, and lost lock once before that at CHECK_IR and just now again at DHARD_WFS so I put the detector in DOWN and set Observatory Mode to MICROSEISM and will try locking again in ~30 minutes with hopefully better luck and lower microseism.
