Urata, on\nbehalf of the HETE WXM Team;\n\nwrite:\n\n>From an analysis of the HETE FREGATE data for GRB030519B (=H2716), we\nfind that the peak flux over 5 s is ~ 8 x 10^-7 erg cm-2 s-1 in the\n7-30 keV energy band and ~ 7 x 10^-6 erg cm-2 s-1 in the 30-400 keV\nenergy band.  Similarly, we find that the fluence of the burst is 7 x\n10^-6 erg cm^-2 in the 7-30 keV energy band and ~ 6 x 10^-5 erg cm-2 in\nthe 30-400 keV energy band.  Thus this burst is bright and its fluence\nis large (the latter is in the top 1% of those for all BATSE bursts).\nIn addition, a preliminary spectral analysis of the FREGATE data\nindicates that the spectral slope of the burst at high (> 100 keV)\nenergies is > -2, and thus E_peak > 400 keV.\n\nIn GCN Circular 2235 (Lamb et al. 2003), the date of the burst was\nreported as 3 May 2003 and the width of the WXM localization rectangle\nwas reported as 24 arcminutes.  These are incorrect; the date of the\nburst is 19 May 2003 and the width of the localization rectangle is\n17.4 arcminutes.  Neither affect the WXM or the HETE/IPN error boxes\nreported in GCNs 2235 (Lamb et al. 2003) and 2237 (Hurley et al. 2003);\nthe size of the latter is ~35 square arcminutes.\n\nFollow-up observations of this burst are strongly encouraged.",
