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) SGR_A 123.3 0420-014 39.5 3C273B 155.1 3C274 148.5 1334-127 176.0 3C345 115.2 1741-038 122.3 1921-293 101.7 P-VYCMA 88.4 P-RLEO 114.9 P-SCRB 132.1 P-RUHER 130.6 P-UHER 131.5 P-AHSCO 130.1 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.
