A. Crain, D. Foster, M. Nysewander, and A. 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
18.3) on an unfiltered image taken on Nov. 1.30 UT
with the 0.41-m 'PROMPT 3' telescope located at Cerro
Tololo. The new object, which is also present at mag
approximately 18.4 in an image taken on Nov. 2.12,
is located at R.A. = 5h00m56s.13 +/- 0".2, Decl. =
-13°24'57".9 +/- 0".2 (equinox 2000.0), which is about
11".9 east and 21".9 north of center of the galaxy
MCG -02-13-37. Nothing is visible at this position
in fifteen stacked archival images taken between 2010
Jan. 1.13 and Dec. 20.19 (limiting mag 20.0).
J. Anderson and T. De Jaeger, Universidad de Chile;
and G. Pignata, Universidad de Andres Bello, on behalf
of the Millennium Center for Supernova Science, report
on optical spectroscopy (range 450-880 nm) of 2011hq
that was obtained on Nov. 16.3 UT with the SOAR telescope
(+ Goodman instrument). Cross-correlation with a library
of supernova spectra using the "Supernova Identification"
code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024)
gives good matches to type-Ia supernovae a few months
past maximum light.
