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) J1146+3958 79.8 J1128+5925 70.9 J1613+3412 120.4 J1203+4510 80.6 J1229+6335 76.4 J1606+2717 126.4 J1156+4443 79.6 J1237+6517 76.5 J1605+2728 126.1 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.
