Dear colleagues,
I have just concluded the analysis of my 2017, Mar 25/26 unfiltered CCD
photometry session of MASTER OTJ075450.18+091020.2. Observations were made
at CBA Belgium Observatory,  using a 0.40-m /f10.0 telescope and STT-3200ME
CCD camera, under a clear sky. The resulting light curve clearly shows the
presence of superhumps with an amplitude of 0.21 mag. A period analysis
using the ANOVA and PDM methods (Peranso), yields a combined preliminary
superhump period of 0.0673 +/- 0.0002d, hence establishing this object as a
new SU UMa-type dwarf nova. The object was at mag 17.0 (unfiltered).

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

Best regards

Tonny Vanmunster
