COVER LETTER: Target: PGC032873 Primary phase-reference calibrator: J1058+4304 Secondary phase-reference calibrator: J1058+4248 (10:58:00.753096, +42:48:44.15638, J2000) Fringe-finder: 4C39.25 Calibrator for e-MERLIN: 3C286 Note: Here is another candidate of the secondary p-ref calibrator: J1059+4051 (10:59:51.90608208, +40:51:14.1996044, J2000) This candidate is farther from the target but relatively compact. I am unsure which one is better. These two secondary p-ref calibrators are not included in the catalogues. Add manually.

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) PGC032873 146.7 J1058+4248 146.2 4C39.25 147.6 J1058+4304 145.9 3C286 132.6 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.
