The solar corona can cause unstable phases for sources too close to the Sun. 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) J1159-2148 115.1 J1159-2228 115.1 J1212-2221 118.0 J1215-1731 117.5 J1218-0119 112.6 J1222+0413 111.1 J1224+0330 112.0 3C273B 113.6 J1636+2112 136.5 J1641+2257 134.8 J1642+2523 132.4 J1644+1813 139.5 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.
