     Kyoto U. team, Itoh-san and Tonny Vanmunster have reported
observations. This object shows (super?)humps, and the most likely
period is 0.04034(9) d.
     Because the amplitude of the outburst is only 1.9V, this outburst
may be an ordinary superoutburst. In addition, the SDSS colors are
red. Further observations are encouraged.
