A long outburst was recorded from 2016 July 21 to 28.
Short outbursts were observed on 2017 January 1,
2018 December 4-5, 8-9 and 12-13, 2019 May 2-4,
and 2020 March 22-24.
The three outbursts recorded in 2018 December may have
been rebrightenings following a missed superoutburst.
However, as outbursts seem to occur quite frequently,
this looks more like an SU UMa-type than a WZ Sge-type
dwarf nova.

Time-resolved photometry during the next long outburst
is encouraged -- and also astrometry when the dwarf
nova is bright again.

Regards,
Patrick
