[vsnet-alert 20256] NSV14681: new SU UMa-type dwarf nova - updated superhump period

[Tonny Vanmunster]

Dear colleagues,
 
I have just concluded the analysis of a 2016, Oct 25/26 unfiltered CCD photometry session of NSV14681. 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 still shows the presence of superhumps with an amplitude of 0.27 mag. Combined with my observations of 2016, Oct 22/23, a period analysis using the ANOVA and PDM methods (Peranso), yields a refined superhump period of 0.0889 +/- 0.0016d. The object was at mag 15.2 (unfiltered) during the Oct 25/26 session.

 

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

Best regards
Tonny
