W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R.Starr, on behalf of the GRS/Odyssey GRB team, report:
Ulysses, Konus-Wind, and Mars Odyssey-HEND observed this burst at 16451 s.
As observed by Ulysses, it had a duration of about 150 seconds, a 25-100 keV fluence of approximately 1.4E-05 erg/cm2, and a peak flux of approximately 1.0E-06 erg/cm2 s over 0.25 seconds.
We have triangulated it to two alternate, preliminary, 3 sigma error boxes each with approximate area 110. square arcminutes whose coordinates are:

There is a chance that the ambiguity can be resolved by further processing. These error boxes may be improved.
A map will be posted shortly at ssl.berkeley.edu/ipn3/020708. Note that somewhat larger, four-sided error boxes were circulated in the GCN socket message, for reasons related to the formatting of those messages. The above, smaller error boxes are the more precise ones.

GCN notice #1451
K. Hurley, on behalf of the Ulysses GRB team,
E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team,
D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, and
T. Cline, on behalf of the Ulysses and Konus-Wind GRB teams, report:
This burst (GCN 1450) was also observed by RHESSI. The RHESSI data, as well as additional Konus-Wind data, indicate that the second error box is the correct one:

                       RA(2000)         DEC(2000)
