We have been informed by the Central Bureau for Astronomical Telegrams (IAU Circular 8316) that Mark Armstrong, Rolvenden, England, discovered an apparent supernova at CCD magnitude about
14.3 on unfiltered images taken on April 7.120 and 7.847 UT using a 0.35-m reflector.  The new object was confirmed by Martin Mobberley, Cockfield, England, on an unfiltered CCD image taken by him on April 7.831 UT.

SN 2004bd is located at:

R.A. = 11h 39m 42.18s,  Decl. = +31o 54' 31.8" (equinox 2000.0),

which is approximately 4.7" west and 1.2" south of the center of NGC 3786.
