Dear colleagues,

I have just concluded the analysis of my 2018, Feb 18/19 unfiltered CCD photometry session of MASTER OT J061904.85+291606.4. Observations were made at CBA Belgium Observatory,  using a 0.40-m f/10.0 telescope and STT-3200ME CCD camera, under a clear sky . The resulting light curve clearly shows the presence of superhumps with an amplitude of 0.19 mag. A period analysis using the ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a combined superhump period of 0.0760 +/- 0.0009d, hence establishing this object as a new SU UMa type dwarf nova. The object was at mag 16.00 (unfiltered) on Feb 18th.  

 

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

 

Best regards
Tonny
