Dear colleagues,

I have just finished analysing my unfiltered CCD observations of TCP J03493487+3607319 (aka ASASSN-24hf), obtained on 2024, Dec 23/24, 24/25 and 25/26 at CBA Extremadura Observatory (Spain) 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 regular superhumps with an amplitude of 0.23 mag, establishing TCP J03493487+3607319 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 superhump period of 0.0697 +/- 0.0002d. The object was at mag CV = 16.7 on Dec 26th.

Image calibration and photometry were done using Phoranso, which allowed me to simultaenously measure other variables present in the FOV of this new SU UMa-type dwarf nova.

I will send my observations to AAVSO, CBA and VSNET for further analysis.

With kind regards,

Tonny
