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) J1007-021 139.3 J1035-201 144.1 J1045-294 142.1 J1046-293 142.2 J1048-191 147.3 J1105-394 138.5 J1121-071 158.1 J1124-040 158.8 J1125-353 144.3 J1127-075 159.4 J1133-040 160.9 3C279 178.3 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.
