I have come across a paper by Kato et al “Photometric study of new southern SU UMa-type dwarf novae
and candidates: V877 Ara, KK Tel and PU CMa”
So I am occasionally imaging PU CMa as it may be coming up for a superoutburst in January/February. The other two will be better placed in the spring.
In the meantime, I have joined G Poyner and IL Walton in following V1159 Ori.
