Lost to weather. Clouds only for first half, then snow flurries start about 8 UT. About 8 cm of dry powdery snow had accumulated by mid-morning, with drifts up to 20 cm on the roof.

Night was used by Doug to pump LBC-Blue on the telescope with his new hanging pump assembly.

We also did some major cleaning of the control room.


Torsten gave us a new version 2.2.9 of GCS and the GCSGUI.


00:23 We verified the parity of the DX Primary Mirror temperature plot by spraying CO2 snow on the lower right corner.

06:00 Spent about 3 person-hours cleaning the control room.

08:00 We tested that the AGW4 guide camera still has good images.
