SUPERNOVA 1994U IN NGC 4948
Timothy Barker, Department of Physics and Astronomy, Wheaton
College, reports the discovery of a supernova during a CCD survey
with a 0.36-m telescope, the object being located very close to the
centre of NGC 4948 (R.A. = 13h02m.3, Decl. = -7o41', 1950.0).
When found on June 27.10 UT, SN 1994U was at mag about 14; it was
not visible on a similar image taken on June 10 (limiting mag about
16.0) or on other images taken over the last 14 months.
