ASASSN-13ck: stage A superhumps and mass ratio

   Oksanen team (Arto Oksanen, Caisey Harlingten) and Berto Monard
reported new observations.  In addition to Masi team's data
(Gianluca Masi, Francesca Nocentini, Patrick Schmeer),
these observations clearly showed evolving superhumps.
The period of stage A superhumps has been determined to be
0.05671(3) d, if we exclude Masi's data (now asking for
confirmation).  The mass ratio derived from this period is
low (0.06) using the method arXiv 1307.5588.  The object
appears to be close to the period minimum.
