  • 15:20 Started walk-through, telescope checkout.
  • 15:30 LBC Blue filled with LN2
  • 16:00 Test preset completed successfully.
  • Encoders reset (worked the first time)
  • 16:07 AGW motors homed (not stopped or restarted)
  • 16:12:29 Telescope at zenith, rotator at 341, turned over to LUCIFER Team

16:14 Weather: outside temp 0.7C, RH 81% and rising, 10m/s wind (SMT 1m/s). Currently completely cloudy, occasional snow this afternoon.

We remained closed the entire night. LUCIFER Team continued with calibration unit, working on flexure compensation and other things.

Astrometric data from a previous night shows no trends with time or EL, and rms variations in scale throughout the night are at the 0.028% level. There is marginal evidence for slightly larger variations from one night to the next (0.04%), but more analysis of exisiting data is needed.
