[vsnet-alert 26874] 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-alert 26870] Re: V618 Sgr fading
by Taichi Kato 14 Jul '22

14 Jul '22

Re: V618 Sgr fading This looks like an eclipse. There were deep (more than 3 mag) fading events in 2018 Aug.-Oct. and 2020 July-Oct. A period of 710 d has been inferred. This symbiotic variable is faint at minimum and eclipses may be prominent only during outbursts when the disk becomes bright. Multicolor photometry of this eclipse may be helpful in understanding the structure of the disk.
