Dear colleagues, I have just finished analysing my unfiltered CCD observations of ASASSN-24cg (aka Gaia DR3 4378710224740797312 and TCP J16454549-0257144) obtained on 2024, Apr 03/04 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 0.34 mag, establishing ASASSN-24cg as a new SU UMa-type dwarf nova. A period analysis, using the ANOVA, Lomb-Scargle, Lomb-Scargle GLS and PDM methods (Peranso 3.0) yields a combined superhump period of 0.0613 +/- 0.0007d. The object was at mag CV = 13.5 on Apr 4th. Image calibration and photometry were done using a beta version of Phoranso. I will send my observations to AAVSO, CBA and VSNET for further analysis.
