[vsnet-outburst 18839] ASASSN-15sc: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,
 
I’m currently (2015, Oct 31) doing unfiltered CCD photometry of ASASSN-15sc. An intermediate analysis of the observations, made at CBA Belgium Observatory using a 0.35-m f/6.3 telescope and STT-3200ME CCD camera under clear skies, clearly reveals the presence of superhumps, establishing this target as a new SU UMa-type dwarf nova. The superhump amplitude is approx 0.2 mag. A preliminary period analysis using the ANOVA method (Peranso), yields a period of 0.0584 +/- 0.0006d. 

A more refined period analysis will be made upon completing the current observing session.

 

Further observations are encouraged.

Observations will be sent to CBA and VSNET for analysis.

Best regards
Tonny
