Castellani, Verona, Italy reports the discovery by Raffaele Belligoli, Flavio Castellani and Vittorio Andreoli, in the course of the ISSP Italian Supernovae Search Project, of an apparent nova on a co-added 4500sec unfiltered images taken with a Moravian G4-9000 KAF CCD unfiltered, from Monte Baldo Observatory (Ferrara di Monte Baldo, Verona, Italy), with the 0.4m f.8 Ritchey-Chrétien telescope, obtained on 2023 February 10.7911 UT. The new object is located at RA 01 34 52.97 DEC +30 47 14.5 (equinox 2000.0) Apparent magnitude about 17.5 in host Galaxy M33. No stellar source is visible at the position of the transient in our past images including reference image dated 2023 February 9.8032	2023TNSTR.327....1F	N

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.
