TITLE: GCN GRB OBSERVATION REPORT
NUMBER: 2221
SUBJECT: IPN triangulation of GRB030509 (single error box)
DATE: 03/05/09 16:44:59 GMT
FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu>
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.
