D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, 
and A. Zehnder, on behalf of the RHESSI GRB team, report:

Ulysses, Mars Odyssey-HEND, RHESSI, HETE-FREGATE, and Konus-Wind
observed this GRB at 19804 seconds.  As observed by Ulysses, it had a
duration of approximately  0.3 seconds, a 25-100 keV fluence of
approximately 2E-07 erg/cm2, and a peak flux of approximately  8E-07
erg/cm2 s over 0.25 seconds.

We have triangulated it a preliminary, 3 sigma error boxes 
with approximate area 9 square arcminutes whose coordinates are:

    RA(2000)                 DEC(2000)
ERROR BOX CENTER:  8 h  7 m 46.09 s     21 o 14 '  17.73 "  (CENTER)
ERROR BOX CORNER 1:  8 h  7 m 45.73 s     21 o 12 '  40.07 "  (CORNER)
ERROR BOX CORNER 2:  8 h  7 m 56.62 s     21 o 11 '  40.15 "  (CORNER)
ERROR BOX CORNER 3:  8 h  7 m 35.56 s     21 o 16 '  55.47 "  (CORNER)
ERROR BOX CORNER 4:  8 h  7 m 46.46 s     21 o 15 '  55.39 "  (CORNER)

A Chandra NRA-accepted target of opportunity observation of this
error box is being requested.  

This error box may be improved slightly.
