CU Vel superoutburst: superhump detection by Greg Bolt!

Dear Colleagues,

   Greg Bolt has sent us a time-series run of CU Vel taken on December 11.
The light curve clearly shows superhumps, confirming that the present
outburst is a superoutburst.

   In addition to superhumps, there is strong evidence of super-QPOs with
relatively large amplitudes.  The light curve just looks like the first
night observation of the superoutburst of EF Peg in 1991 (Kato (2002),
PASJ 54, 87; VSNET preprint at
http://vsnet.kusastro.kyoto-u.ac.jp/pub/vsnet/preprints/EF_Peg/ ).

   The similarity of the pattern of super-QPOs and early-stage superhumps
with that of EF Peg may suggest these features may be closely associated
with long-period SU UMa-type dwarf novae with relatively rare superoutbursts.

   Further observations throughout the current superoutburst are very
strongly encouraged!

Regards,
Taichi Kato
