TK4 quickly faded! Dear Colleagues, The CCD run at Kyoto (M. Uemura and R. Ishioka) on Nov. 2 indicates that the object had already faded (if the reported outburst was a real one). Although precise measurement of the magnitude should require further analysis, the object may have faded by more than 2-3 mag since the last visual sightings on Nov. 1. Such a rapid fading is totally unexpected, and we encourage further intensive observations of this object. Regards, Taichi Kato VSNET Collaboration team
