   The object showed long outbursts relatively
regularly in 2016-2017 (cycle length 56 d).
There were, however, short outbursts between them.
The object may be either extreme SS Cyg-type object
(with long outbursts) or an object like V503 Cyg.

   Detailed observations to search for superhumps
during long outbursts are desired.
