We unfortunately needed to close just before midnight because unforecasted clouds with radar appeared just to our west and slightly overhead. As I closed the telescope, I witnessed a strange vibration that seemed to come from the altitude axis. More details are given in the log body. The clouds persisted the rest of the night and we were unable to reopen. ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?

I am going to take the APOGEE dome flats and BOSS cals now, in case I need to close quickly. 05:34Z - Closed the enclosure but remained ventilating. Hopefully the clouds will pass and I can open back up. There was a strange vibration stemming from the telescope as I closed and moved the telescope from 5 degrees to 30. Initially thinking that it might be coming from the rotator since Dmitry noted some odd behaviors a few days ago, I went through some troubleshooting measures to identify where it could be coming from. No odd voltages were seen, but I did power cycle amplifiers for each axis. The vibration would start immediately when the altitude axis was initialized and would cease a few moments after the brake would be set. Maybe it was tied to the wind baffle? By the time I wanted to try power cycling the wind baffle control switch, I lost the ability to recreate the vibration. I'm not sure what caused it. 11:17Z - The clouds are just getting more plentiful unfortunately. They persisted the rest of the night. Started APOGEE morningcals and turned off the FPS. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: 0.1020 0.1030 Axial B: 0.0018 0.0018 Axial C: -0.1760
