COVER LETTER: Dear EVN friends, This is the schedule for the 18cm NME and ftp fringe-test on 16 June 2015, involving 15 antennas: Eb Wb Jb1 On85 Mc Nt Tr Sh Sv Zc Bd Hh T6 Sr Ar (+Wd). The NME uses a standard setup with 512 Mbps and consists of long integrations on strong calibrators J0854+2006, J0011+0823, J0126+2559, 4C39.25, and 0234+285. Six ftp tests are scheduled: (1) 10:05:58 UT (scan 2, 2 sec, J0854+2006) (2) 10:20:58 UT (scan 9, 2 sec, J0011+0823) for Ar (3) 11:25:58 UT (scan 12, 2 sec, J0126+2559) for Ar (4) 11:40:58 UT (scan 25, 2 sec, 4C39.25) (5) 12:23:58 UT (scan 34, 2 sec, J0854+2006) (6) 12:54:58 UT (scan 34, 2 sec, 0234+285 ) for Ar Please make sure that the autoftp is set up correctly. Good luck with the session and see you on Skype!

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) J0011+0823 78.9 J0126+2559 56.5 0234+285 40.5 J0854+2006 45.7 4C39.25 50.7 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.
