Dear Yusuke, I think TESS is currently observing this object, and it should detect the outburst. There are 41 sectors in the archive (observed between 2019 and 2025), but I haven't detected any outbursts in them.

ASASSN-26ab = ASASSN-25fj; updated superhump period
Lesedi telescope at the SAAO, Josch Hambsch, and Peter Starr reported further time-resolved observations of ASASSN-26ab = ASASSN-25fj. The ordinary superhump period is updated to 0.054915(8) d. The system is currently in the stage-B ordinary superhump phase. *Note that the ASASSN team somehow assigned a new name ASASSN-26ab.
