Ivarsen, J. Haislip, 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 16.6) on an
unfiltered image taken on Aug. 28.09 UT with the 0.41-m 'PROMPT 5' telescope
located at Cerro Tololo.  The new object, which is also present at mag
approximately 16.1 in an image taken on Aug. 29.04, is located at R.A. =
20h13m55s.16 +/- 0".2, Decl. = -1o09'22".2 +/- 0".2 (equinox 2000.0), which
is about 11".3 east and 4".9 north of center of the galaxy UGC 11527.
Nothing is visible at this position on archival images taken on Aug. 24.99
(limiting mag 18.0) and Aug. 12.01 (limiting mag 18.5).  The variable was
designated PSN J20135516-0109222 when it was posted at the Central Bureau's
TOCP webpage and is here designated SN 2011fj based on the spectroscopic
report below.

     J. L. Prieto, Carnegie Observatories, reports than an optical spectrum
(range 370-930 nm; resolution 0.7 nm) of PSN J20135516-0109222 = SN 2011fj was
obtained on Aug. 30.1 UT with the du Pont 2.5-m telescope (+ WFCCD) at Las
Campanas Observatory.  The spectrum shows an almost-featureless blue continuum
and a faint, broad H-alpha emission feature (FWHM approximately 14000 km/s),
characteristic of young type-II supernovae.
