and Helicon-Coronas-F GRB teams, report:

Ulysses, Mars Odyssey (HEND and GRS), Helicon, and Konus-Wind  observed
this GRB at 14496 seconds (GCN 1632).  We have triangulated it to two
alternate, preliminary 3 sigma error boxes, each with area ~80 sq.
arcminutes:

    RA(2000)                              DEC(2000)
 ERROR BOX CENTER:  14 h 51 m 55.41 s    -56 o 13 '  55.57 " 
 ERROR BOX CORNER 1: 14 h 53 m 22.84 s    -56 o  3 '  41.08 " 
 ERROR BOX CORNER 2: 14 h 54 m 23.38 s    -55 o 59 '  49.55 " 
 ERROR BOX CORNER 3: 14 h 49 m 22.86 s    -56 o 28 '   9.56 " 
 ERROR BOX CORNER 4: 14 h 50 m 26.16 s    -56 o 24 '  13.51 " 

OR

 ERROR BOX CENTER: 9 h 32 m 54.34 s    -60 o 29 ' 43.75"
 ERROR BOX CORNER 5: 9 h 31 m  3.13 s    -60 o 21 '  40.45 " 
 ERROR BOX CORNER 6: 9 h 29 m 50.52 s    -60 o 19 '  16.57 "  
 ERROR BOX CORNER 7: 9 h 36 m  3.62 s    -60 o 40 '   9.89 " 
 ERROR BOX CORNER 8: 9 h 34 m 47.79 s    -60 o 37 '  46.96 " 

There is a strong probability, which cannot be quantified, that the
latter is in fact the correct position.  We will attempt to verify
this as soon as possible.

These error boxes may be improved.
