The WXM\nflight localization was correct and was reported in a GCN Position\nNotice at 12:07:02 UT, 49 sec after the beginning of the burst.\n\nGround analysis of the WXM data for the burst produced a refined\nlocation, which was reported in a GCN Position Notice at 13:19:54 UT,\n73 minutes after the burst.  The WXM localization SNR was 14.  The WXM\nlocation can be expressed as a 90% confidence circle that is 10\narcminutes in radius and is centered at\n\nRA = 00h 26m 47s, Dec = +18d 59' 13\" (J2000).\n\nGround analysis of the SXC data for the burst produced a further\nrefinement in the location, which was reported in a GCN Position Notice\nat 14:39:51 UT, 154 minutes after the burst.  The SXC localization SNR\nwas 9.  The SXC location can be expressed as a 90% confidence circle\nthat is 2 arcminutes in radius and is centered at\n\nRA = 00h 26m 57s, Dec = +18d 55' 44\" (J2000).\n\nThe SXC localization may be improved.\n\nIn the FREGATE 8-40 keV band, the burst had a duration of ~100 seconds.\nIn the WXM 2-25 keV band, the burst also had a duration of ~100\nseconds.\n\nA light curve for GRB021004 is provided at the following URL:\n\nhttp://space.mit.edu/HETE/Bursts/\n\nThis message is citable.",
