No new source with respect to the\nDSS is observed within the 2 arcminute radius IBAS error circle\nin coadded V-band exposures down to the following 5-sigma\nmagnitude upper limit:\n\nFilter  T_range(days)  Exp(sec)  5sigUL\nV       2.25-2.38      4932      20.4\n\nWe note that there was a high image background in the region of\nthe IBIS error circle due to the presence of a Vmag=9 star within\nit (as mentioned by Torii, GCN 4193).",
