Dear colleagues,
I have just concluded the analysis of a 2016, Oct 12/13 unfiltered CCD photometry session of MASTER OTJ054746.81+762018.9. Observations were made 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 with an amplitude of 0.22 mag. A period analysis using the ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a combined superhump period of 0.0555 +/- 0.0011d, hence establishing this object as a new SU UMa-type dwarf nova. The object was at mag 17.0 (unfiltered).

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

Best regards
