LS And: missed superoutburst in 2022!
(I'm checking ASAS-SN)
The outburst occurred close to the solar conjunction and was apparently not monitored by visual observers.
The outburst of clearly of a WZ Sge-type one whose peak was missed. There was no rebrightening (object probably close to the period minimum).
The object is currently still on the fading tail, about 1.5 mag brighter than in quiescence before the 2022 outburst. Observations of the white dwarf will still be interesting before it cools down.
