MAXI J1659-152: periodicity update

   Kyoto team (observer: Ohshima-san) and Kiyota-san have reported additional
observations.  The object is still slowly fading (no dramatic fading).
Guided by the candidate period in ATEL 2926, we obtained an optical
period of 0.1005(2) d and a maen amplitude of 0.2-0.3 mag.
There is some (needs confirmation) indication of an asymmetric (faster rise)
profile.
