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) NGC4278 86.4 NGC4203 89.3 J0927+3902 123.2 J1159+2914 90.4 J1207+2754 88.3 J1214+3309 89.4 J1217+3007 87.3 J1228+3128 86.0 J1228+3706 88.7 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.
