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) G22.357 75.6 G25.411 74.3 G45.473 66.4 G73.060 61.8 G75.761 60.1 3C345 101.7 J1825-0737 77.2 J1905+0952 68.3 J2015+3710 61.1 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.
