IW And: heartbeat state now

ASAS-SN data:
https://asas-sn.osu.edu/light_curves/941827e5-fb54-493b-92fd-571b21233cd3

   Currently in beautiful heartbeat state since Aug. 20.
This state is probably first time clearly seen
in this object.

   The current state has been detected also by visual
and CCD observers.  However, I must point out that
a deep fading was not properly recorded by one observer,
probably by prejudice (and possibly by copy-and-paste
observations).
