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. = -13o24'57".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.
