OT J002656.6+284933: second rebrightening

   Roger Pickard has detection of the second
rebrightening on Nov. 25 (16.8 mag).
S. Shugarov's team has also provided observations
before this rebrightening.   The data by Shugarov's
team detected possible eclipse-like fadings.
Until very recently, multiple rebrightenings
were restricted to WZ Sge-type objects.
V1006 Cyg in 2015 showed two rebrightening
(Kato et al. 2016).  The present detection of
multiple rebrightenings strengthen the similarity
between WZ Sge-type dwarf novae and long-Porb
SU UMa-type dwarf novae.  If more "eclipse-like"
fading are detected, we can estimate the mass ratio
directly using stage A method.  Further observations
are strongly encouraged.
