ASASSN-15hd: ordinary superhumps

   Itoh-san, Crimean Astrophys. Obs. team, Enrique de Miguel
and Michael Richmond have reported new observations.
The superhump signal detected by Osaka Kyoiku U. team
has been confirmed.  The period was longer up to Apr. 28
(0.05729(5) d).  The amplitudes of superhumps have already
grown to 0.2 mag now.  If the period up to Apr. 28 represents
stage A superhumps, the mass ratio is estimated to be 0.09.
This identification may be modified as more observations
become available.
