VLBI project bg170a was observed with the GBT.
The C-band part (4.9 GHz) went very smoothly.

The K-band part (22.2 GHz) had some problems on startup
which led to some loss of observing time.
Later in the run, it started raining, so the last 2 hours or so
are probably not usable.

22:30 UT  4.9 GHz   Tsys ~ 27 K,  phase cal amplitudes about 1.5%

01:50 UT  22.2 GHz  Tsys ~ 90 K

01:52 UT to 02:12 UT  off source due to software problems

03:15 UT  22.2 GHz  Tsys ~ 190 K  and raining

phase cals were not present for the 22.2 GHz part of the run.

Disk pack VIPSU-04 was used.  We will hold on to it for
a few days to add part of the next project.
