• Some testing of the trajectory interface this week.
• Normal spacecraft tracking next week.
• Reviewing MIT/LL science goals for FY 09 on Wednesday.

Data has been moved from /home/gbtdata to the archive. The science data archive is now up to 2.7Tb Gbtlogs has also been cleaned out, leaving only the last 6 months of logs in /home/gbtlogs.

The archive is being re-taped on SDLT600 tapes to ensure continuity and save on shelf space. The SDLT600 tapes hold 3 of the AIT3 tape images. All science data is still available online.

• Nothing to report

• Conceptual Design Review February 27 and 38 preparations under way.

• • • Todd's new OOF preprocessing script can now open Ka/CCB OOF maps (from Dec 2006). Need to confirm the details of the port and IF labeling.

A busy week. We supported 22 projects in 41 observing sessions, including 2 VLB runs. The telescope was scheduled for 8.5 hrs for maintenance, 6 hrs of software regression testing, 2.5 hrs of Zpec tests, and 1 hr for PF1 receiver checkout. 20.5 hrs were spent with the telescope at half speed due to cold weather. Lost time was 17.6 hrs (about 11.5%), of which 11.5 hrs were due to the wind storm. The major causes of lost time were:

• Winds (6 instances) -- 11.5 hrs
• Elevation Roller Bearing -- 3.9 hrs
• Observer script errors (2 instances) -- 0.9 hrs
• Az Transducers -- 0.3 hrs
• Low Temperatures / half speed switch over (2 instances) -- 0.3 hrs
• Astrid (3 instances) -- 0.3 hrs
• Archivist (5 instances) -- 0.3 hrs
• Snow -- 0.1 hrs

The observing script problems were an attempt to observe with the wrong K-band beams, and a script that did not remove the L-band notch filter. The Archivist errors are those we were expecting from our discussions from last week.

Zpec had test time at the start of the week. Mustang's progress is reported below.

• Working on final FPGA design for the combining FPGA. THis design will combine the 2 polarizations, accumulate spectra, scale them, and output in 8 bit chunks over the 10 Gb Ethernet.
