[vsnet-campaign-dn 14661] Re: Next superoutburst expectation of TCP J21040470+4631129

[反保雄介]

Dear collaborators,

This is Yusuke from Kyoto University.

As I previously emailed, the next superoutburst of a dwarf nova TCP
J21040470+4631129 is expected within this month.
Continuous snapshots and, once it underwent a superoutburst, time-resolved
photometry is encouraged.

Also, since Japan is still in rainy season, world-wide observations are
really appreciated.

Best regards and stay safe.
Yusuke
