[vsnet-outburst 20294] ASASSN-16ow: new SU UMa-type dwarf nova

[Tonny Vanmunster]

Dear colleagues,

I have just concluded the analysis of tonight’s 2016, Dec 14/15 unfiltered
CCD photometry session of ASASSN-16ow. Observations were made at CBA
Belgium Observatory,  using a 0.35-m f/6.3 telescope and STT-3200ME CCD
camera, under clear skies but with strong moonlight. The resulting light
curve clearly shows the presence of superhumps with an amplitude of 0.25
mag. A preliminary period analysis using the ANOVA, PDM and Lomb-Scargle
methods (Peranso), yields a combined superhump period of 0.0864 +/-
0.0028d, hence establishing this object as a new SU UMa-type dwarf nova.


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

Best regards
Tonny
