This transient was observed on 2023 02 11.78103 by Andrea Mantero from C77 - Bernezzo Observatory using 0.25-m f/4 reflector - CCD Atik 314L Scale 1,33"/pixel. Stack of 6 unfiltered b1x1 frames x 90 sec. guiding exposures, show the source at 16.9 Mag.(limiting magnitude 19.5) end figures for astrometry were AR. 01,34 52.95 s DEC. +30,47 14.0" position measured from reference stars UCAC-4 catalogue.

Flavio Castellani, Claudio Balcon and Vittorio Andreoli reports: We obtained BVRI photometry of PNV J01345297+3047145 (AT 2023bne) with 0.4m telescope + Moravian G4 CCD full frame located in Novezzina (Italy), date 2023/02/11.7868 B=17.11 ; V=17.04 ; R=17.01 ; I=16.84 (Vphot AAVSO photometry tool). Color index B-V=0.07 is similar to cataclysmic variable (CV) Z Cam B-V=0.05 (Bruch 1984) at maximum. We also obtained two low resolution spectra (2x2400s , R=100) by 0.2m telescope on 2023-02-11.772 UT, the spectrum shows a blue continuum with no features above noise level. These characteristics are compatible with those of a CV in outburst.
