The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of AT 2017fut, discovered by F. Ciabattari, E. Mazzoni, M. Rossi (Italian Supernovae Search Project ISSP) in PGC 5530.
The observation was performed with the Asiago 1.82 m Copernico Telescope equipped with AFOSC (range 340-820 nm; resolution 1.4 nm).
Survey Name | IAI Name | Discovery date (UT) | Discovery mag | Observation (UT) | Type | z | Notes|
AT 2017fut | SN 2017fut | 2017-07-29 01:55:12 | 17.7 |2017-08-02. | SN Ia | 0.042803 | (1) |
(1) The spectrum is consistent with that of a Type Ia SN events around one week past maximum light, at a redshift 0.042803, according to the redshift of the host galaxy PGC5530 (Giovanelli and Haynes, 1993, AJ 105, 1271). Thus the expansion velocity of the ejecta, as deduced from the position of SiII 635.5 nm minimum, is about 9900 km/s.
Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
