report:
Post-processing analysis of HETE data has revealed the presence of
XRF 040701, a bright XRF. The burst was detected at 13:00:55 UT
and had a duration of roughly 60 seconds. The XRF has been localized
to a circle of radius 8' centered at
RA = 20h 47m 46.3s, dec = -40d 14m 13s (J2000).
Preliminary spectral analysis shows the burst can be best fit with a
power law of index 2.395 +/- 0.3; the 2-25 keV energy fluence is
4.5 +/- 0.8 x 10^-7 erg/cm2.
Details of this burst can be found on the HETE web page at
