Dear colleagues,
I have just finished analysing my unfiltered CCD observations of ASASSN-22ho, obtained on 2022, June 02/03 at CBA Belgium Observatory, using a 0.40-m f/10.0 telescope and QHY-286M CMOS camera under clear skies.
Regular superhumps with an amplitude of 0.35 mag are very clearly visible in the resulting light curve, establishing ASASSN-22ho as a new SU UMa-type dwarf nova. A period analysis using the ANOVA, Lomb-Scargle, Generalized-Lomb-Scargle and PDM methods (Peranso 3.0), yields a combined (long) superhump period of 0.0902 +/- 0.0025d. The object was at mag CV = 16.5 on Jun 03rd.
I will send my observations to AAVSO, CBA and VSNET for further analysis.
Best regards Tonny
