Further to Lipunov et al.���s discovery of a transient by MASTER in
ESO 138-006 which is in the localisation region of G211117
(see GCN 18835), at (RA, Dec) = 16h 54m 20.77s
-61d 52m 58.0s on 2016-01-06.06807 UT.
PESSTO, the Public ESO Spectroscopic Survey for Transient Objects
(see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org)
reports a classification spectrum. The transient is a type II supernova,
most likely a II-P, at +30d, with a redshift (z=0.018) consistent with that of the
likely host (ESO 138-006).
Observations were performed on the ESO New Technology Telescope
at La Silla on 2016 Jan 08, using EFOSC2 and Grism 13 (3985-9315A,
18A resolution). Classifications was done with SNID (Blondin & Tonry, 2007,
ApJ, 666, 1024) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383).
