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.

Sincerely,

Alexander Tarasenkov

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.

Best regards,
Yusuke
