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) AT2019AALC 122.3 J1521+0420 123.0 J1521+0517 122.9 J1159+2914 152.9 J1504+1029 127.0 J1751+0939 85.9 J2203+3145 40.7 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.
