ASASSN-15bp: stage A superhumps and mass ratio

   Enrique de Miguel, Kiyota-san, William Stein, Josch Hambsch
and Osaka Kyoiku U. team have reported new observations.
Ordinary superhumps became prominent since Jan. 31.
The period of stage A superhumps has been 0.05729(3) d.
Using the updated period of early superhumps (0.05572(3) d),
we have obtained a mass ratio of 0.07.
The slow growth of stage A superhumps appears to be
consistent with this low q.
