[vsnet-alert 20218] MASTER OT J021315.37+533822.7: new long-period SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,
 
I have just concluded the analysis of 3 nights of unfiltered CCD photometry observations of MASTER OT J021315.37+533822.7, i.e. 2016, Oct 03/04, 04/05 and 05/06, with a total of 956 observations over a time span of 2.3 days. 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 0.42 mag. A period analysis using the ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a combined (long) superhump period of 0.1062 +/- 0.0003d. The object had an average mag of 16.9 (unfiltered).


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

Best regards
Tonny
