  LS And was a transient discovered in 1971 in the M31 region and it has been
argued whether it could be an intergalactic nova or a dwarf nova. Using the
Zwicky Transient Facility (ZTF) data, I found that the object underwent the
second known outburst in 2022 April. The behavior was that of a WZ Sge-type
dwarf nova with a long fading tail and the light curves of the 1971 and 2022
outbursts matched very well. The light curves suggest that LS And is a typical
WZ Sge-type dwarf nova near (but before reaching) the period minimum of
cataclysmic variables. The true observed peak of the 1971 outburst was likely
12.2 mag. The outburst parameters were similar to those of other WZ Sge-type
dwarf novae. The fading tail lasts more than a year and the object is still
currently on this tail. There was a hint of 0.5-mag temporary brightening on
the fading tail and the object appears still active after the outburst.
