S. Ciroi, A. Siviero (DFA Universita di Padova), L. Tomasella, E. Cappellaro, M. Turatto, S. Benetti (INAF - Osservatorio Astronomico di Padova) report/s a classification of object: SN 2019hsw

Type: SN II
Redshift: 0.0055

Remarks: The low S/N spectrum (because of scattered clouds and bright Moon) shows a blue continuum and hints of broad H Balmer features consistent with a young type II SN. We also detect narrow Halpha and [OIII] emission lines from a nearby HII region from which we derive a redshift of 0.0055 in agreement with z=0.0058 reported for NGC 2805 by Almeida et al. 2011, ApJ 735 via NED.

The following Classification spectrum was provided:

Obsdate: 2019-06-19 20:47:48
Instrument: BC-Ekar
Telescope: Asiago Ekar Telescope

Remarks: low S/N, 9X3min spectra to minimise the noise due to scattered clouds and bright Moon.
