report:

Ulysses, Mars Odyssey, Konus, RHESSI, and INTEGRAL (SPI-ACS) observed
this very intense, 8 s long burst at 52035 s.  Spectral information
will be given in a forthcoming GCN Circular.  We have triangulated
it to an ~ 46 sq. arcmin. error box (3 sigma), whose coordinates are

    RA(2000)                 DEC(2000)
 18 h 10 m 01.78 s     58 o 08 '  47.67 "  (CENTER)
 18 h 09 m 36.85 s     58 o 00 '  55.18 "  (CORNER)
 18 h 09 m 47.45 s     57 o 57 '  22.44 "  (CORNER)
 18 h 10 m 16.89 s     58 o 20 '  22.15 "  (CORNER)
