COVER LETTER: Dear EVN friends, This is the schedule for the 1.3cm FTP-FT on March 04 2014, involving 19 stations: Eb Wb Jb1 On25 Mc Nt Tr Sv Zc Bd Ir Ur Sh Hh Ys, as well as Md Td Yd (Mc Tr and Ys with DBBC) and Sh65. The session uses a standard setup with 512 Mbps and consists of three ftp fringe tests, interspersed with a longer set of phase referencing scans on 3C 84 (~25 Jy source at 5 GHz), and a weaker calibrator. The three ftp fringe-test scans, start at: (1) 14:07:30 UT (scan 2, 2 sec) (2) 14:57:20 UT (scan 20, 2 sec) (3) 16:52:50 UT (scan 62, 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) J0313+4120 74.7 3C84 76.0 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.
