The schedule consists of long integrations on calibrator J0804+2006. We shall use J0905+2052 for phase referencing. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:13:00 (scan 2, 2 sec, J0804+2006) 12:35:00 (scan 4, 2 sec, J0804+2006) 13:05:00 (scan 6, 2 sec, J0804+2006) 13:35:00 (scan 10, 2 sec, J0804+2006) 14:05:00 (scan 14, 2 sec, J0804+2006) 14:35:00 (scan 18, 2 sec, J0804+2006) Good luck with the session!

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J0905+2052 59.6 J0854+2006 57.4 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
