Two ftp tests are scheduled: ~12:09 UT (scan 2, 4 sec, J0854+2006) ~12:51 UT (scan 6, 4 sec, J0854+2006) Please make sure that the autoftp is set up correctly. 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) J0854+2006 68.2 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.
