[vsnet-alert 19554] ASASSN-13az: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,
 
Tonight (2016, Mar 03/04), I have been doing unfiltered CCD photometry of ASASSN-13az. Observations were made at CBA Belgium Observatory,  using a 0.35-m f/6.3 telescope and STT-3200ME CCD camera, under clear skies (afterwards hazy). 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 0.25 mag. A period analysis using the ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a combined period of 0.0838 +/- 0.0016d. 


Further observations are evidently encouraged.

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

Best regards
Tonny
