BO Cet: likely superhumps

   Kyoto U. team, Itoh-san, Josch Hambsch (and some
from Tonny Vanmunster) reported observations.
The current variation appears to be expressed by
a period of 0.1487(7) d, which is similar to
the superhump period in 2020 Nov.
(see vsnet-alert 24906).
The conclusion, however, is less certain than in
2020 due to short runs and potentially overlapping
orbital variations.  Nightly observations by Hambsch
strongly suggest the presence of superhumps
(smooth variations, in contrast to the behavior
before the current bright outburst).
