BW Scl : post superoutburst stage

 We have received further observations from Berto Monard.
According to observations, this object showed superhumps 
continuously. However, sometimes peaks other than the 
original superhump peaks were seen.
 O-C diagram implies that this object underwent further
period change when the abrupt decline ended. After that,
the superhump period is 0.05508 (5) d. This is near that of
stage B superhumps.
 In the stage, which preceded the post outburst stage, 
the superhump period was 0.05422(18) d. Interestingly,
this period is rather similar to that of early superhumps 
and orbital period. It is interesting that such variations 
were seen only in the declining.

 Further observations are encouraged!
