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 VSNET Collaboration team
