MAXI J1659-152: slow fading and possible periodicity

   Kyoto team (observer: Ohshima-san), Maehara-san and Kiyota-san have
reported further observations.  The data indicate a slow fading trend
at 0.041(5) mag/d, comparable to an optical e-folding time of ~30 d.
Although the short visibility makes unique determination of the period
very difficult, there appear to be ~0.10 d modulations (amplitude 0.2 mag),
using the period in ATEL 2912 (see also vsnet-alert 12230 for periodicity
detected from the optical data).
