OT J043112.5-031452: superhumps weakening

 We have received observations of Jan. 27 from William Stein.
Obtained data shows that variations are apparently weakening.
Additionally according to the period analysis, obtained period
implies that the variations is double peaks and the period is
near orbital period rather than superhump period (0.0330(4) d
is obtained, this seems to be a half of orbital period).
Nonetheless we cannot be sure that superhumps desappeared yet.
Although this object is faint now, please take observations
continuously if you can.
