V503 Cyg superoutburst

   I wished to comment on this a few days ago, but
forgot to mention.  This superoutburst was 140 d after
the previous one.  It is now known whether there
was a missed superoutburst in Feb. (no ASAS-SN data).
This object had a renowned short supercycle
and mass-transfer rate would have changed.
