Resyncs follow tape stoppages and formatter reconfigures. For VLBA DAR stations, total reconfigures and reconfigures during recording are shown. Reconfigures during recording can cause slow correlator sync. Any reconfigure can slow sync at JIVE.

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) J0555+3948 157.2 J0605+4030 155.2 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.
