COVER LETTER:


This is one of three .key files to observe Arp 220 at 18cm, 6cm and 3.6cm
during EVN session I 2023. Arp 220 has two nuclei 1 arcsec apart; we aim
to point right in the middle of them, to get both at the same time.

OPERATOR NOTES:
VLA27: Please use all 27 stations at 18cm.

EFFECT OF SOLAR CORONA

  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:

   J1516+1932         122.6
   J1532+2344         118.2

  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. 
  For common VLBI bands, this is:
