AQ CMi superhumps
Filipp Romanov, Itoh-san and Josch Hambsch have reported
observations. The superhump period of 0.06613(2) d
was obtained. This object was not well observed
(on the contrary to what one might presume) during past
superoutbursts and it is still worth observing.
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

V550 Cyg outburst
Known SU UMa star. Hiraga-san has pointed out that
the identification on the AAVSO chart is wrong.
Not a nearby 17-mag star.
