[vsnet-campaign-dn 16475] TCP J22561804+4109534 rebrightenings
by Taichi Kato 26 Jul '22

26 Jul '22

TCP J22561804+4109534 rebrightenings Tamas Tordai has reported further observations. Five rebrightenings have been recorded up to July 24. The amplitudes, however, are decreasing and frequent small-amplitude rebrightenings resemble those of WZ Sge. This phenomenon is atypical for this orbital period.

[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.
