Re: SW UMa: super QPOs? The result more looks flickering rather than super-QPOs, superimposed on superhumps (likely "late superhumps"). Super-QPOs have much longer stable coherence, as was observed in SW UMa in the past. cf. http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/superqpo.html However, observations in this stage will be very valuable in determining the life-time of this phenomenon.
