E. Paillas, and S. Varela, Universidad Andres Bello; F. Aros, Pontificia

IPMU, University of Tokyo; and D. E. Reichart, J. B. Haislip, J. P. Moore, and
A. P. LaCluyze, University of North Carolina at Chapel Hill, on behalf of the
CHASE project (which is part of the Millennium Center for Supernova Science
collaboration), report the discovery of an apparent Supernova (mag
approximately 17.5) on an unfiltered image taken on June 10.10 UT with the
0.41-m 'PROMPT 3' telescope located at Cerro Tololo.  The new object is
located at R.A. = 10h43m28s.19 +/- 0".2, Decl. = -25o51'52".1 +/- 0".2
(equinox 2000.0), which is about 1".3 west and 8".6 north of the center of the
galaxy ESO 501-84.  The variable was designated PSN J10432819-2551521 when it
was posted at the Central Bureau's TOCP webpage and is here designated SN
2013eg based on the spectroscopic confirmation reported below.  Additional
CCD magnitudes for 2013eg:  Apr. 11.09, [18.5 (CHASE); June 10.96, 17.2
(CHASE); 13.471, 17.7 (J. Brimacombe, Cairns, Australia; 41-cm telescope +
infrared filter; bandpass > 700 nm; position end figures 28s.19, 52".6; image

     K. Takats and G. Pignata, Universidad Andres Bello; and P. Lira, J.
Martinez, and J. Mejia, Universidad de Chile, on behalf of the Millennium
Center for Supernova Science, report optical spectroscopy (range 360-920 nm)
of PSN J10432819-2551521 = SN 2013eg, obtained on July 11.98 UT with the Las
Campanas 2.5-m du Pont telescope (+ WFCCD).  Cross-correlation with a library
of supernova spectra using the "Supernova Identification" code (SNID; Blondin
and Tonry 2007, Ap.J. 666, 1024) shows that 2013eg is a type-Ia supernova
about three weeks after maximum light.
