GCN notice #2221
K. Hurley, on behalf of the Ulysses GRB team,
E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team,
A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, and
T. Cline, on behalf of the Ulysses and Konus GRB teams, report:
Ulysses, Konus-Wind, and INTEGRAL (SPI-ACS) observed this GRB at 21024 seconds.
As observed by Ulysses, it had a duration of approximately 9 seconds, a 25-100 keV fluence of approximately 1.2E-05 erg/cm2, and a peak flux of approximately 7.5E-06 erg/cm2 s over 0.50 seconds.
We have triangulated it to a preliminary, 3 sigma error box whose area is approximately 275 sq. arcmin. and whose coordinates are:
```
    RA(2000)                 DEC(2000)
  5 h 26 m 24.19 s      7 o  8 '  47.66 "  (CENTER)
  5 h 29 m 29.24 s      6 o  5 '   7.72 "  (CORNER)
  5 h 29 m 32.20 s      6 o  7 '   4.37 "  (CORNER)
  5 h 23 m 14.12 s      8 o 11 '  55.65 "  (CORNER)
  5 h 23 m 16.87 s      8 o 13 '  58.39 "  (CORNER)
```
This error box may be improved, but it is not known at this point whether this event was observed by Mars Odyssey, and thus whether a significantly smaller error box can be derived for it.
GCN notice #2222
K. Hurley, on behalf of the Ulysses GRB team, reports:
The confidence region for one dimension of the error box of this burst (GCN 2221) was underestimated. The correct, 3 sigma error box coordinates are:
RA(2000) DEC(2000) 5 h 26 m 24.19 s 7 o 8 ' 47.66 " (CENTER) 5 h 39 m 9.75 s 2 o 55 ' 0.26 " (CORNER) 5 h 39 m 12.94 s 2 o 56 ' 49.85 " (CORNER) 5 h 12 m 55.57 s 11 o 46 ' 51.06 " (CORNER) 5 h 12 m 57.81 s 11 o 49 ' 7.90 " (CORNER)
The area of this error box is approximately 1100 square arcminutes.
I regret any inconvenience caused by this mistake.
