A relatively rare outburst started on 2021 September 6 according to recent ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) data: https://asas-sn.osu.edu/sky-patrol/coordinate/1348a779-1ab5-4f79-a58c-183ed1... https://asas-sn.osu.edu/sky-patrol/coordinate/3e9155c6-4573-4917-9f6c-4c0bde...
An apparent (short) rebrightening during the relatively fast decline (faster than that of a standard UGSU superoutburst) occurred on September 14.
A previous outburst (= ASASSN-17lo) was recorded from 2017 August 29 to September 7 by the ASAS-SN Sky Patrol.
