[vsnet-alert 18545] CRTS J164950.4+035835: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,

 

CRTS  J164950.4+035835 turns out to be a new SU UMa type dwarf nova. This
morning (2015, Apr 14/15), I obtained unfiltered CCD photometry observations
of this target at CBA Belgium Observatory,  using a 0.35-m f/6.3 telescope
and STT-3200ME CCD camera. The sky was very clear, resulting in a light
curve with a time span of 2.8 hours. It clearly shows the presence of
superhumps, hence establishing this target as a new SU UMa-type dwarf nova.
The sumperhump amplitude is approx 0.15 mag. A period analysis using the
ANOVA, Lomb-Scargle and PDM methods (Peranso), yields a period of 0.076 +/-
0.001 d only. Further observations are evidently encouraged.

 

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

 

Best regards

Tonny
