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.

SDSS J001153.08-064739.1: positive Pdot
Tonny Vanmunster, Josch Hambsch and Filipp Romanov have
reported observations. The mean superhump period is
0.10446(2) d. Pdot is positive +8(3)*10^(-5),
which is rare for an object in the period gap.
