I report the discovery of probable supernova in anonymous galaxy.
The new object was found on archival images taken with the 2.54-m INT
at La Palma and obtained from the ING Archive.
The host galaxy with V=20.8 and R=20.1 mag is located at
R.A. = 9h54m02s.93, Decl. = +69d12'42".5 (equinox 2000.0).
Probable supernova is located at R.A. = 9h54m02s.84, Decl. = +69d12'42".6
(equinox 2000.0), which is 0.5" west and 0.1" north of the center
of the host galaxy.
The new object is clearly visible on co-added images from four nights
as well as on single images used for co-added images.
Available magnitudes (obtained with the 2.54-m INT, unless otherwise
noted):
Sloan r'-band: 2002 Dec. 24.184 UT, [22.7; 2003 May 9.883, [21.9;
23.960, [22.1; Jun. 3.897, 20.6; 5.900, 20.4.

Note that V-band images from the Subaru telescope were obtained from
the SMOKA science archive.
