OT J105756+092315.3: new data and period
Gianluca Masi and Kiyota-san have reported new observations.
The object is fading rather rapidly (for an SU UMa-type dwarf nova).
Masi's data (two nights) look flatter than Kiyota-san's data.
An analysis has yielded a potential periodicity (as reported by Ohshima-san)
with a period of 0.03579(3) d, but the amplitude is relatively small
(0.03 mag, smooth profile, though). It is not clear whether the period
is somehow related to the binary parameters.
