14477 2023-02-23 12:59:27 Panos Charalampopoulos Panos Charalampopoulos, Maximilian Stritzinger, Eric. Y. Hsiao NUTS2 SN Ia 0.014 1 NUTS2 P. Charalampopoulos (Turku), M. Stritzinger (Aarhus), and E. Y. Hsiao (FSU), on behalf of the NUTS2 and POISE collaborations reports the classification of SN 2023cjd. Inspection of an optical spectrum obtained with the Nordic Optical Telescope on 2023-03-23 (i.e., MJD 59998.04) reveal it to be a type Ia supernova. Comparison with a library of supernovae spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), indicate SN 2023cjd resembles SN 2002bo around a week before peak brightness. From the minimum of the Si-II 6355 Angstrom absorption feature and assuming a redshift to the host galaxy of 0.014 (Jones et al. 2009, The 6dF Galaxy Survey Data Release 3), we compute a Doppler blue-shifted expansion velocity with an excess of 17,000 km/s. 2023TNSCR.426....1C
