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)
J0713+43 85.4
J0927+39 60.6

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.
For common VLBI bands, this is:
327 MHz 117. deg
610 MHz 81. deg
1.6 GHz 45. deg
2.3 GHz 36. deg
5.0 GHz 23. deg
8.4 GHz 17. deg
15.0 GHz 12. deg
22.0 GHz 9. deg
43.0 GHz 6. deg
