The observation started at 2003 September 13, 17:08:24 UT (87 s after trigger), and 40 s integration was repeated. In a stacked frame (12 x 40 s), no new object brighter than about 14.5 mag (USNO A2.0 red) is identified within the central 30x30 arcminutes area of the WXM position (Seq_Num 2). Further analysis is in progress."
