The WXM localization SNR was 6.\nThe WXM location can be expressed as a 90% confidence circle that\nis 20 arcminutes in radius and is centered at\n\nRA = 00h 17m 23s, Dec = -01d 37' 00\" (J2000).\n\nIn the WXM 2-25 keV band, the burst had a duration of ~13 seconds.\nThe spectrum of the burst is soft, making estimates of its peak\nflux and fluence uncertain.\n\nA light curve for GRB021021 is provided at the following URL:\n\nhttp://space.mit.edu/HETE/Bursts/GRB021021.\n\nThis message is citable.",
