[vsnet-alert 18613] Re: ASASSN-13ak: new SU UMa-type dwarf nova

[Ian Miller]

I also detected superhumps on this object during a 4.6h time-series last night.  Their amplitude was about 0.2C.  The ANOVA method (Peranso) yielded a period of 0.0866 +/- 0.0042d and the mean magnitude was 14.7C.

 

Best regards, 

Ian.
