[vsnet-alert 19417] ASASSN-16af: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,
 
Last night (2016, Jan 13/14), I have been doing unfiltered CCD photometry of ASASSN-16af. Observations were made at CBA Belgium Observatory,  using a 0.35-m f/6.3 telescope and STT-3200ME CCD camera, under moderate skies with broken clouds. 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 0.27 mag. A period analysis using the ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a combined period of 0.0623 +/- 0.0005d. 

Further observations are evidently encouraged.

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

Best regards
Tonny
