   A coincidence.  I noticed the same fading yesterday.  Ohshima-san
regularly observed this object just *before* and *after* this event.
It was an astronomical loss such an event went unnoticed real-time!
However, the fading doesn't very much look like an eclipse of
a symbiotic binary.  The object shows pulsation-like variations other
than this epoch, making the event resembling a deep minimum of
something like an RV Tau-type variable, the period is too long for that,
though.
