Dear colleagues,
I have just finished analysing my unfiltered CCD observations of TCP
J17374270+4915116, obtained over the past 7 nights between 2024, Dec 23/24
and 29/30 at CBA Extremadura Observatory (Spain) using a 0.40-m f/5.1
telescope and SX-46 CCD camera under clear skies. The object started to
develop superhumps on Dec 28/29, which further developed on Dec 29/30.
The resulting light curve clearly shows the presence of regular superhumps
with an amplitude of 0.25 mag, …
[View More]establishing TCP J17374270+4915116 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 0.0589 +/- 0.0002d. The object was at mag CV = 14.6 on
Dec 30th.
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
