Dear colleagues,
I have just finished analysing my unfiltered CMOS observations of TCP J03383192+2712288 obtained on 2024, Mar 08/09 at CBA Belgium Observatory using a 0.40-m f/10.0 telescope and QHY-268M CMOS camera, and on 2024, Mar 10/11 at CBA Extremadura Observatory using a 0.40-m f/5.1 telescope and SX-46 CCD camera. In both cases, skies were not entirely clear.
The resulting light curve clearly shows the presence of superhumps with an amplitude of 0.24 mag, establishing TCP J03383192+2712288 as a new SU UMa-type dwarf nova. A period analysis, using the ANOVA, Lomb-Scargle, Conditional Entropy and PDM methods (Peranso 3.0) yields a combined superhump period of 0.0542 +/- 0.0010d. The object was at mag CV = 16.4 on Mar 10th.
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.
Best regards
Tonny
