The session uses a setup with 512 Mbps and consists of 3 ftp fringe tests, interspersed with a longer set of scans on 3C345 (source showing ~14 to 2 Jy correlated fluxes at 3.6cm). The three ftp fringe-test scans, start at: (1) 10:43:28 UT (scan 2, 2 sec) (2) 11:55:58 UT (scan 15, 2 sec) (3) 13:17:28 UT (scan 29, 2 sec) See you on Skype group chat and 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) 3C345 62.4 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.
