Castellani, Verona, Italy reports the discovery by Raffaele Belligoli, Flavio Castellani and Claudio Marangoni, in the course of the ISSP Italian Supernovae Search Project, of an apparent nova in two 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 2018 October 13.822 and 13.845 UT. The new object is located at RA 00 42 40.12 DEC +41 17 27.3 (equinox 2000.0) Apparent magnitude about 17.5 in host Galaxy M31. Nothing is visible at this position on the reference image of 19Th september 2018. Offset '43.7W 81.3N' from the center of M31 (see link to discovery image below). Apparent magnitude 17.5 V (err +/- 0,2).

Andrew Howell, Curtis McCully, Stefano Valenti Global SN ProjectSN Ia0.0411Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several Type Ia supernovae around the maximum light at the redshift of 0.041. At the redshift of 0.041, corresponding to the distance modulus of 36.26, the absolute magnitude in V-band taken at 2018-10-08 23:48:10 is -19.04 mag which is consistent with the Ia classification and its phase. We measure the SiII velocity of 11,000 km/s from the absorption lines.
