O. Yaron, Weizmann Institute for Science; D. Young, QUB; and I. Manulis,
Weizmann Institute for Science, on behalf of the Public ESO Spectroscopic
Survey for Transient Objects (PESSTO) collaboration, report the discovery of
a supernova (magnitudes U = 18.4 +/- 0.1, B = 17.9 +/- 0.1, V = 17.5 +/- 0.1,
R = 17.3 +/- 0.1, i = 17.2 +/- 0.1) in the galaxy ESO 154-G10.  All
observations were performed on the ESO 3.5-m New Technology Telescope (NTT)
at La Silla on 2014 Nov. 16.28 UT, using the EFOSC2 UBVRi filters.  The
position of the transient is R.A. = 2h45m09s.27, Decl. = -55d44'16".9 (equinox
2000.0), which is 5".0 east and 9".0 north of the R-band nucleus of the galaxy
(position end figures 08s.68, 25".8).  This variable was discovered in the
course of observing SN 2013fc (cf. CBET 3644) in ESO 154-G10.  The last
non-detection was from an NTT/SOFI K_s-band image taken on 2014 Oct. 14.3.

Wyrzykowski, Warsaw Observatory, on behalf of the PESSTO collaboration (see
website URL http://www.astronomerstelegram.org/?read=6739), report that an
optical spectrogram (range 369-932 nm) of SN 2014eg in the galaxy ESO 154-G10,
obtained on 2014 Nov. 23.25 UT with the 3.6-m New Technology Telescope (+
EFOSC2 Grism 13; range 398.5-931.5 nm; 1.8-nm resolution) at La Silla, shows
it to be a 1991T-like type-Ia supernova.  Adopting a recession velocity of
5586 km/s for ESO 154-G10 (Loveday et al. 1996, Ap.J. Suppl. 107, 201; via
NED), the best fit to the spectrum found by SNID (Blondin and Tonry 2007,
Ap.J. 666, 1024) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383) is to
the spectrum of SN 1991T at roughly seven days before maximum light.
