29 Aug '24

ASASSN-24fo: new WZ Sge-type dwarf nova ASASSN-24fo was discovered on 2024-08-25.14 by the ASAS-SN team with an ~8.5 mag outburst amplitude. Sjoerd Dufoer and Josch Hambsch reported time-resolved observations. These observations detected a double-waved variation with an amplitude of 0.04 mag and a period of 0.05691(5) d. Therefore ASASSN-24fo is a new WZ Sge-type dwarf nova Further observations are encouraged. Best regards, Yusuke -- ---------------------------------------------- South … [View More]

Dear colleagues, I have just finished analysing my unfiltered CCD observations of TCP J19470832-0924198, obtained on 2024, Aug 13/14 at CBA Extremadura Observatory using a 0.40-m f/5.1 telescope and SX-46 CCD camera under clear skies. The resulting light curve clearly shows the presence of superhumps with an amplitude of 0.30 mag, establishing TCP J19470832-0924198 as a new SU UMa-type dwarf nova. A period analysis, using the ANOVA, Lomb-Scargle, Generalized-Lomb-Scargle and PDM … [View More]
