RX J0558.3+6735: fading Dear Colleagues, We have partly analyzed the Kyoto data (observers: M. Uemura and R. Ishioka) on Apr. 2. The data show that the object faded by 0.4-0.5 mag/d. The hump-like structures seen on Apr. 1 became less prominent. We apparently need further observations before making a conclusion on the classification of the object (UG type is the presently acceptable classification). Further follow-up observations are encouraged (if the object is an SU UMa-type star, the object may brighten again to a genuine superoutburst). Other possibilities (orbital humps etc.) need to be examined by future observations. Regards, Taichi Kato VSNET Collaboration team
