I was moving from 80 to 12 deg and motion error occurred at 73 degrees. After an axis init we had no further problems during the night. There were clouds and radar returns at the beginning of the night which cleared up nicely around 7pm. Skies remained clear with good seeing. I seemed to have forgotten to note the seeing in the focus script, but it was 1.15" in r band at 21:17. ---- And now for a little Christmas tune!
