SUPERNOVA 2006bp IN NGC 3953
     S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata, Japan) of an apparent supernova (mag 16.7) on
unfiltered 20-s CCD exposures taken around Apr. 9.60 UT (limiting mag
19.5) using a 0.60-m f/5.7 reflector.  The new object has continued to
brighten rapidly, as indicated by Itagaki's additional magnitudes:
Apr. 9.6136, 16.7; 9.6689, 16.4; 9.7383, 16.0; 9.7835, 15.8.
SN 2006bp is located at R.A. = 11h53m55s.74, Decl. = +52o21'09".4
(equinox 2000.0), which is 62" east and 93" north of the center of
NGC 3953.  Nothing was visible at this location on Itagaki's images
taken on 2005 Mar. 19 and 2006 Mar. 23 (limiting mag 19.0).
