From observations of several photometric standards taken the\nsame night, we find that the star at coordinates 00:54:37.96,\n+01:13:00.7 J2000 (i.e. south west of the offset star in the finder from\nGCN #2766) has B = 18.28 mag and V = 17.35 mag.  From these, we estimate\nthat the afterglow had a B-V colour of approximately 0.28 +/- 0.03 mag\naround 2004 Oct 6.58 UT.",
