SUPERNOVA 2014cl IN IC 217 = PSN J02160910-1156026

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 Institute for Astrophysics), report the discovery of an apparent
supernova (mag approximately 17.5) on an unfiltered image taken on June 16.40
UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo.  The new
object, which is also visible at mag approximately 17.2 in an image taken on
June 17.43, is located at R.A. = 2h16m09s.10 +/- 0".2, Decl. = -11o56'02".6
+/- 0".2 (equinox 2000.0), which is about 19".8 west and 25".9 south of the
center of the galaxy IC 217.  Nothing is visible at this position on archival
images taken on 2013 Dec. 12.06 (limiting mag 18.5).  The variable was
designated PSN J02160910-1156026 when it was posted at the Central Bureau's
TOCP webpage and is here designated SN 2014cl based on the spectroscopic
confirmation reported below.

     K. Takats, F. Bufano, F. Olivares, and G. Pignata, Universidad de Andres
Bello, on behalf of the Millennium Institute of Astrophysics, report that an
optical spectrogram (range 450-880 nm) of PSN J02160910-1156026 = SN 2014cl
was obtained on July 12.3 UT with the SOAR telescope (+ Goodman Spectograph).
Cross-correlation with a library of supernova spectra using the "Supernova
Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) gives a
good match to the type-IIb supernova 1993J at a month past maximum light.
