[vsnet-alert 24121] Re: TCP J21040470+4631129 another bright outburst!

[Keisuke Isogai]

This outburst should be a superoutburst and must be
showing growing superhumps now. However, we can
observe this object only for 2-3 hours before sunrise.
It is encouraged to observe this object on many sites.
