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) 0243-05 157.4 0958+32 85.9 1146+53 81.1 3C84 154.5 3C138 144.8 J0920+4441 96.9 J1310+3220 54.8 3C286 51.1 J1407+2827 46.5 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.
