[vsnet-alert 20636] OT J034515-015216: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,
 
I have just concluded the analysis of my unfiltered CCD photometry session of OT J034515-015216 from 2017, Jan 25/26. Observations were made at CBA Belgium Observatory,  using my new 0.40-m /f10.0 telescope (still in deployment mode) and STT-3200ME CCD camera, under a clear sky. The resulting light curve shows the presence of superhumps with an amplitude of 0.15 mag. A period analysis on the detrended light curve, using the ANOVA, PDM and Lomb-Scargle methods (Peranso), yields a combined preliminary superhump period of 0.0659 +/- 0.0004d, hence establishing this object as a new SU UMa-type dwarf nova. The object was at mag 16.2 (unfiltered).

 

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

Best regards
Tonny
