The solar corona can cause unstable phases for sources too close to the Sun. 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) J0019+7327 62.9 J0021+7150 62.5 J0030+7037 61.5 J0157+7442 57.3 J0203+1134 44.7 J0204+1514 43.3 J0204-1701 59.5 J0209+1352 42.6 J0219-1842 58.1 J0222-1615 56.0 J0225+1846 37.6 J0357+2319 15.7 J0401+2110 14.9 J0403+2600 14.6 J0412+2305 12.2 J2145+1115 103.6 J2147+0929 104.0 J2148+0657 104.9 J2151+0709 104.0 J2155+2250 96.1 J2212+2355 92.2 J2217+2421 91.0 J2225+2118 90.5 J2236+7322 70.2 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.
