The Central Bureau for Astronomical Telegrams (CBET 1315, D.W.E. Green, editor) announced the discovery of a bright apparent supernova in NGC 7793 by L.A.G. "Berto" Monard of Pretoria, South Africa. The supernova, SN 2008bk, is located approximately 2.3 arcminutes north of the nucleus of NGC 7793, a bright flocculent spiral galaxy of type Scd. Monard measured the supernova at magnitude 12.6 +/- 0.2 at 2008 March 25.141 (JD 2454550.641). This supernova has not yet been spectrally classified, but the galaxy is undergoing active star formation and a core collapse supernova is possible.
The supernova is located at RA: 23 57 47.5 , Dec: -32 33 24 (J2000)
