Following the Pan-STARSS discovery (Smartt et al, GCN 18394) of candidates
in the G184098 northern error box,  PESSTO, the Public ESO Spectroscopic
Survey for Transient Objects (see Smartt et al. 2015, A&A, 579,
40 http://www.pessto.org), reports that PS15cbm is a type Ia supernova a
t z=0.06 at +2-3w past maximum light.

All observations were performed on the ESO New Technology Telescope at
La Silla on the night of 2015-10-03, using EFOSC2 and Grism 13
(3985-9315A, 18A resolution). Classifications were done with SNID (Blondin &
Tonry, 2007, ApJ, 666, 1024). Classification spectra can be obtained
from http://www.pessto.org (via WISeREP).
