VLBI project BK114G, at 22 GHz with Effelsberg, VLA, and VLBA,
was observed with the GBT.  Mostly everything went well.

The first peak/focus scan (1740-1748 UT) had a large offset,
so the operator repeated it to make sure we had a good
measurement.  Hence the two scans following the peak
were missed (1749-1750 UT).

The very tight scheduling seemed to result in several scans
with less than 10 seconds on source, and possibly a few
being missed altogether.

The power levels immediately following configuration changes
were out of nominal ranges for a few minutes until the operators
adjusted them.  But I think they were still within the range of the
BBC autoleveling, so probably this will not affect the data.

Tsys was about 40 - 50 K;  
the weather was good: mostly clear with a little haze.
Phase cal levels were 2-8 %, during those times when
they were used.

Tapes VLBA0662 and VLBA1221 are being shipped to Socorro today.
