ASASSN-22ak outburst (V3101 Cyg analog?)

The outburst behavior is rather atypical.

All outbursts look like superoutbursts. The object looked like dormant before the exceptionally bright (13.1 mag) outburst in 202 Jan. Might be an object similar to V3101 Cyg (=TCP J21040470+4631129). ASASSN-22ak have much longer outbursts compared to "rebightening"-type superoutbursts in V3101 Cyg. An AM CVn star would also be a candidate considering the short recurrence time of superoutbursts. Detailed observations are encouraged anyway.
