[vsnet-campaign-dn 16471] TCP J22561804+4109534 second rebrightening
by Taichi Kato 20 Jul '22

20 Jul '22

TCP J22561804+4109534 second rebrightening Tamas Tordai reported the second rebrightening on July 19-20. See [vsnet-alert 26866] It would be worth noting that the period 0.065 d is long for a WZ Sge star. If this is indeed a WZ Sge star, it must be a period bouncer.

[vsnet-campaign-dn 16468] Re: TCP J22561804+4109534: new WZ Sge-type dwarf nova

It would be worth noting that the period 0.065 d is long for a WZ Sge star. If this is indeed a WZ Sge star, it must be a period bouncer. Period bouncers tend to have smaller amplitudes of ordinary superhumps and 0.14 mag seems to be a bit large. I would propose to assign the WZ Sge classification after confirmation of a small Pdot and/or rebrightenings.
