behalf of the GRS-Odyssey GRB team, report:
Ulysses and Mars Odyssey (GRS) observed this burst at 33817 s
+/- 55 s (the uncertainty is due to the fact that no near-Earth
spacecraft has reported this event yet). From the limited data
available at this time, the duration appears to be >~350 s,
the 25-100 keV fluence ~5 x 10^-6 erg/cm^2, and the peak flux
over 0.5 s ~2 x 10^-6 erg cm^2 s^-1.
We have triangulated it to a preliminary annulus centered
at RA, Decl.(2000)=168.621, +16.880, whose radius is 65.036 +/- 0.019
degrees (3 sigma).
This localization can be improved, particularly if the event
was observed by any near-Earth spacecraft.
