GOTO065054.49+593624.51: type-E rebrightening WZ Sge star?
Recent time-resolved observations reported to VSNET/AAVSO, especially those by Tonny Vanmunster, David Messier, Nikola Antonov, and Ian Sharp, show growing superhumps after its recovery from the short-lived dip around 2024-10-19.
Using these time-resolved observations after the dip, the superhump period is obtained as 0.06323(2) d, consistent with previous Tonny's reports to VSNET alerts.
These features suggest that this ongoing brightening event is likely a type-E rebrightening (dip caused by the disk transition from early to ordinary superhumps) and thus GOTO065054.49+593624.51 would be a new period bouncer candidate showing a WZ Sge-type dwarf nova outburst.
For type-E rebrightenings and period bouncers, see.g. Kimura et al 2018
Further observations are encouraged.
