and M. Capaccioli, G. Covone, and M. Paolillo, Universita Federico II, Napoli,
on behalf of the SUDARE/VOICE collaboration (cf. CBET 3236), report the
discovery of two supernovae on r-band images taken during their supernova
search program with the European Southern Observatory's VLT Survey Telescope
(+ Omegacam).

 SN       2013 UT       R.A. (2000.0) Decl.        Mag.     Offset
 2013go   Oct. 21.2    3 27 44.643  -28 29 13.55   20.4    1".2 W, 4".4 N
 2013gp   Oct. 21.2    3 26 55.507  -28 46 45.75   21.6    1".2 E, 1".1 N

A spectrogram of SN 2013go, obtained on Oct. 29.2 UT with the Las Campanas
Observatory Clay Telescope (+ LDSS3; range 450-1020 nm, resolution 0.3 nm),
shows the typical features of a type-Ia supernova; cross-correlation with a
library of supernova spectra using the "Supernova Identification" code (SNID;
Blondin and Tonry 2007, Ap.J. 666, 1024) shows that SN 2013go resembles SN
1991T at 50 days after B-band maximum light at z = 0.076.
     A spectrogram of SN 2013gp, obtained as above on Oct. 29.2, shows that
the object is a type-Ia supernova; cross-correlation with a library of
supernova spectra using SNID shows that SN 2013gp resembles SN 1981B at
around three weeks after B-band maximum light at z = 0.236.
