[vsnet-alert 20542] CSS110124:082604+113821: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,
 
I have just concluded the analysis of tonight’s 2017, Jan 05/06 unfiltered CCD photometry session of CSS110124:082604+113821. Observations were made at CBA Belgium Observatory,  using a 0.35-m f/6.3 telescope and STT-3200ME CCD camera, under a very clear sky. The resulting light curve clearly shows the presence of superhumps with an amplitude of 0.20 mag. A period analysis using the ANOVA, PDM and Lomb-Scargle methods (Peranso), yields a combined preliminary superhump period of 0.0721 +/- 0.0005d, hence establishing this object as a new SU UMa-type dwarf nova. The object was at mag 15.2 (unfiltered).

 

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

Best regards
Tonny
