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) J2237+4216 86.2 J2248+4502 89.5 GJ873 88.8 J0110+5404 113.9 GJ53B 113.7 J0124+5618 116.1 J0237+2848 127.2 3C454.3 74.8 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.
