SUPERNOVA 2003ei IN UGC 10402
     Further to IAUC 8131, J. Graham and W. Li report the LOTOSS
discovery of an apparent supernova on unfiltered KAIT images on
May 19.4 (mag about 17.2) and 20.4 UT (mag about 16.9).  SN 2003ei
is located at R.A. = 16h28m40s.30, Decl. = +12 46'05".8 (equinox
2000.0), which is 4".6 west and 9".5 north of the nucleus of the
northern component of UGC 10402, an interacting galaxy pair.
A KAIT image taken on Mar. 31.5 showed nothing at this position
(limiting mag about 19.5).
