[vsnet-outburst 25334] Next superoutburst expectation of TCP J21040470+4631129

Next superoutburst expectation of TCP J21040470+4631129

Dear all,

A dwarf nova TCP J21040470+4631129, which underwent its main superoutburst
in July 2019, is expected to exhibit the next rebrightening superoutburst
in mid ~ end of next month. This object has shown three superoutbursts so
far even during the rebrightening phase. (Observational summary of this
object until its 5th rebrightening is given in Tampo et al. 2020.)
https://ui.adsabs.harvard.edu/abs/2020PASJ...72...49T/abstract
Such energetic rebrightenings have never observed so far, and would give a
clue to understanding the physical mechanism of rebrightening phenomena.

Main superoutburst: 12th July 2019 (JD 2458677)
3rd rebrightening: 25th August 2019 (JD 2458721)
5th rebrightening: 9th December 2019 (JD 2458827)
6th(?) rebrightening: 31st March 2020 (JD 2458940)

Since the supercycle of these rebrightenings is ~ 110 days, the next one
will be around 19th July 2020 (JD 2459050). We first want to examine
whether this object truly shows the next superoutburst on the same
supercycle, and then the development of superhumps and superoutburst.

Continuous snapshots and, once it underwent a superoutburst, time-resolved
photometry is encouraged.

Best regards and stay safe
Yusuke
