[vsnet-campaign-dn 15943] MASTER OT J052622.61+734629.7: new SU UMa-type dwarf nova
Dear colleagues, I have just finished analysing my unfiltered CMOS observations of MASTER OT J052622.61+734629.7, obtained on 2021, September 03/04 at CBA Belgium Observatory, using a 0.40-m f/10.0 telescope and QHY-268M CMOS camera under clear skies. Regular superhumps with an amplitude of 0.29 mag are clearly visible in the resulting light curve, establishing MASTER OT J052622.61+734629.7 as a new SU UMa-type dwarf nova. A period analysis using the ANOVA, Lomb-Scargle, Generalized-Lomb-Scargle and PDM methods (Peranso 3.0), yields a combined superhump period of 0.0665 +/- 0.0003d. The object was at mag CV = 16.2 on Sep 04th. I will send my observations to AAVSO, CBA and VSNET for further analysis.
