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) J0031+1507 158.1 J0121+0346 167.0 J0122+0309 166.7 J0257+4338 146.4 J2314+0201 137.6 J0019+2021 154.4 J0121+0422 167.5 J0237+2848 161.4 J0251+4315 147.2 3C454.3 134.6 J2320+0513 139.8 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.
