COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 31st May 2024 involving the following (10) antennas: Jb2 Wb1 Ef Mc On85 Tr Ys Hh Ir Sr The NME uses a standard setup with 4096 Mbps. The schedule consists of long integrations on the calibrator J0854+2006. We shall use J0905+2052 in one scan for phase referencing check purposes. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 2, 2 s, J0854+2006) 12:40:00 (scan 4, 2 s, J0854+2006) 13:10:00 (scan 6, 2 s, J0854+2006) 13:40:00 (scan 8, 2 s, J0854+2006) 14:10:00 (scan 10, 2 s, J0854+2006) 14:40:00 (scan 12, 2 s, J0854+2006) 14:58:00 (scan 16, 2 s, J0854+2006) Good fringes to everyone!

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 62.5 J0854+2006 60.3 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. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
