[vsnet-outburst 28758] ASASSN-22ho: new SU UMa-type dwarf nova
by tonny.vanmunster＠gmail.com 29 Nov '22

29 Nov '22

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.

[vsnet-outburst 28824] ASASSN-18su (super?)outburst (since June 24)
by Patrick Schmeer 28 Jun '22

28 Jun '22

ASASSN-18su (UG) https://www.aavso.org/vsx/index.php?view=detail.top&oid=623474 ASASSN-18su was discovered on 2018 August 17. Unfortunately that outburst could be followed for only few days. After the seasonal gap a very long fading tail can be seen in ATLAS forced photometry data. T. Kato wrote (vsnet-alert 22429): "The Gaia proper motion is comparable to that of OV Boo ... ASASSN-18su looks likely a population II CV candidate." The current outburst was detected by Rod Stubbings at mv= 11.3 on 2022 June 28.537 UT (vsnet-outburst 28822, vsnet-alert 26852). It had already started on June 24 and is 1.5 magnitudes fainter than the 2018 outburst according to ASAS-SN Sky Patrol data: https://asas-sn.osu.edu/sky-patrol/coordinate/52d16cd1-3548-431f-a7fc-326e3… Time-resolved photometry is urgently required.
