[vsnet-alert 28174] TCPJ15030519+2202041: growing superhumps appeared, and will undergo the next superoutburst soon

TCPJ15030519+2202041: growing superhumps will drive the next superoutburst soon Josch Hambsch, Itoh-san, Moriyama-san, and we have observed this object. The object is at about 18.8 mag now, slightly brighter than it was several days ago. Also, we detected a clear superhump tonight. This must be the growing (stage A) superhump. In this situation, this object will undergo the next superoutburst with ordinary superhumps soon. The continuous time-resolved observations are strongly encouraged. Although the current brightness of 18.8 mag is very faint for many observers, this object will brighten to about 15 mag within a few days.
