The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of ASASSN-19ab (AT2019B). The target was supplied by the All Sky Automated Survey for SuperNovae (ASAS-SN, Shappee et al. 2014).
The observation was performed with the Asiago 1.82m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm).
Survey name | IAU name | Host galaxy | Disc. Date (UT) | Obs. Date (UT) | redshift| type | phase | notes
ASASSN-19ab | 2019B | UGC118 | 2018-12-30.125 | 2019-01-07.90 | 0.021 | II | 1 week | 1
(1) Noisy spectrum similar to those of several type II supernovae about one/two weeks after explosion.
The classification was performed using the GELATO (Harutyunyan et
al. 2008, A&A, 488, 383)
and SNID (Blondin and Tonry 2007, ApJ,
666, 1024) tools.
