OT J210950.5+134840: superhump periods

   Okayama U. of Sci. team and Ian Miller have reported further observations.
The data indicate that a major change of the superhump period has happened.
The mean period since May 31 has been 0.05980(4) d and before this was
0.06049(6) d.  This change is most likely attributed to stage A-B transition.
Since the observing window for this object is not very long, observations
at different longitudes are essential for determining correct periods.
Further observations are encouraged.
