[vsnet-alert 26885] Var Ret 2005 likely superoutburst
by Patrick Schmeer 28 Jul '22

28 Jul '22

Variable Reticuli 2005 (UGSU:) https://www.aavso.org/vsx/index.php?view=detail.top&oid=161100 Recent ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) light curve and data: https://asas-sn.osu.edu/sky-patrol/coordinate/38d59ff4-1572-40ef-a0c5-e280e… This long outburst began between 2022 July 16 and 21. It was observed at mag. 13 for five days, followed by a rapid fading on July 27. The outburst was considerably longer than short outbursts of this dwarf nova, but shorter than standard UGSU superoutbursts (~14 days). Regards, Patrick

[vsnet-alert 26883] TCP J22561804+4109534 rebrightenings
by Taichi Kato 27 Jul '22

27 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-alert 26874] TCP J22561804+4109534 second rebrightening
by Taichi Kato 21 Jul '22

21 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.
