Dear colleagues I have just finished analysing my unfiltered CCD observations of TCP J18173469+1803499, obtained during 4 consecutive nights between 2024, Sep 28/29 and Oct 01/02 at CBA Extremadura Observatory using a 0.40-m f/5.1 telescope and SX-46 CCD camera under clear skies. This object was detected by the New Milky Way (NMW) survey Camera-2, operating at the Astroverty astrofarm in Russia, on Sep 27th. Superhumps started to emerge in my data set of 2024, Sep 29/30, and are now clearly present in my last set of observations obtained on 2024, Oct 01/02. That light curve shows regular superhumps with an amplitude of 0.11 mag, establishing TCP J18173469+1803499 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 0.0767 +/- 0.0026d. The object was at mag CV = 13.9 on Oct 02nd. Image calibration and photometry were done using my new photometry software Phoranso 1.0.5.1 which allowed me to simultaenously measure 10 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.
