V1454 Cyg: definite SU UMa-type dwarf nova!

   According to Nakajima-san, very clear superhumps have been
recorded on Dec. 1.  The superhumps were once less apparent
on Nov. 30, indicating that these humps have recently regrown.
Due to the short visibility in the evening, the superhump period
is still difficult to determine, but is likely shorter than
the earlier estimates.  The best candidate periods are
0.062 d and 0.058 d, although other aliases are still viable.
Observations at other longitudes are strongly encouraged,
especially at the present time when then object shows
large-amplitude signals.
