The observations were started \non October 24, at 09:44 UTC (48 min after the burst) and stopped on October, \nat 09:58 UTC. One unfiltered 120 seconds image and one unfiltered 600 seconds image \nwere taken. We detected a very dim uncatalogued optical afterglow object at the position\nof RA 22h 36min 59s.68 and DEC +56o 53' 22\".6   with respect to POSSII F\n(J2000) which is in good correlation with Carole Mundell et al. observation \n(GCN 10063). Upper limit for our observations is >18.7 mag. Quoted upper \nlimit has been derived using POSSII F and USNO-B1.0 field stars as reference.\n                \nFilter              Tmid(s)        Exp(s)     OA Mag (CR) USNO-B1.0\n                \nunfiltered         09:53:11        600         18.2+/-0.4",
