      MASTER OT J030227.28+191754.5: stage A superhumps, eventually
The most recent data by Tonny Vanmunster, Tamas Tordai
and Itoh-san have recorded emerging ordinary superhumps
since 2021 Dec. 30 -- 32 d after the outburst detection!
(The longest record, probably related to the large
outburst amplitude).  The period of stage A superhumps
is 0.0616(2) d (2-d baseline).
The period of early superhumps is 0.059851(5) d.
The corresponding mass ratio is 0.076(10), which will be
updated as more observations become available.
This value corresponds to a "borderline" period bouncer.
