TCPJ06461075+2502415: starting to show superhumps? The most recent data by Itoh-san (Mar. 22) showed brightening and a possible sign of emerging superhumps. Ordinary superhumps appear to be emerging now.

[vsnet-campaign-dn 17056] ASASSN-23bl: new SU UMa-type dwarf nova (now faded)
by Taichi Kato 20 Mar '23

20 Mar '23

ASASSN-23bl: new SU UMa-type dwarf nova (now faded) Josch Hambsch has reported observations (and some from Itoh-san). The object faded to 19.5 on Mar. 18. The light curve suggests that the superoutburst plateau stage B-C was likely observed (when superhump amplitude becomes small). A PDM analysis of the superoutburst plateau yielded the most likely period of 0.06348(5) d and an amplitude of 0.07 mag (Due to the low sampling rate, the waveform became apparent only after the period analysis). The object is likely a WZ Sge star based on the amplitude. The period may suggest multiple rebrightenings if it is the case.
