[vsnet-outburst 20243] CSS J085603.8+322109: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,



I just finished analysing my observations of CSS J085603.8+322109, obtained
on 2016, Nov 28/29 and Nov 29/30, as a result of an unfiltered CCD
photometry session at CBA Belgium Observatory,  using a 0.35-m f/6.3
telescope and STT-3200ME CCD camera, under clear skies. The resulting light
curve clearly shows the presence of superhumps, establishing this target as
a new SU UMa-type dwarf nova. The amplitude is approx 0.30 mag. A period
analysis using the ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a
superhump period of 0.0609 +/- 0.0003d.



The object is rapidly fading from its outburst.



Observations will be sent to CBA and VSNET for further analysis.



Best regards

Tonny
