We report the classification of AT2017fna (=ATLAS17ioz) from a spectroscopic observation
made on 2017 July 20 UT with the Low Resolution Imaging Spectrometer (LRIS)
on the Keck I telescope. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS17ioz | AT2017fna | 23:46:51.85 | -10:27:32.02 | 0.074 | Ia | -3 d | (1)
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
(1) SN 1991T-like object. We measure a Si II 6355 velocity of -9,700 km/s.
