TITLE: GCN CIRCULAR
NUMBER: 17107
SUBJECT: IPN Triangulation of GRB 141125A (short/hard)
DATE: 14/11/27 18:32:37 GMT
FROM: Dmitry Svinkin at Ioffe Institute
K. Hurley and J. Goldsten, on behalf of the MESSENGER NS GRB team,
S. Golenetskii, R. Aptekar, V. Pal'shin, D. Frederiks,
D. Svinkin, and T. Cline on behalf of the Konus-Wind team,
S. Barthelmy, J. Cummings, N. Gehrels, H. Krimm, and D. Palmer,
on behalf of the Swift-BAT team, and
A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C.
Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report:
A short-duration, hard-spectrum GRB 141125A has been observed by
Konus-Wind, INTEGRAL (SPI-ACS), MESSENGER (GRNS), and Swift (BAT), so
far, at about 12781 s UT (03:33:01). The burst was outside the coded
field of view of the BAT.
We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
---------------------------------------------
RA(2000), deg Dec(2000), deg
---------------------------------------------
Center:
127.910 (08h 31m 38s) -29.874 (-29d 52' 28")
Corners:
127.504 (08h 30m 01s) -30.527 (-30d 31' 36")
127.358 (08h 29m 26s) -31.092 (-31d 05' 29")
128.315 (08h 33m 16s) -29.209 (-29d 12' 33")
128.465 (08h 33m 52s) -28.616 (-28d 36' 57")
---------------------------------------------
The error box area is 857 sq. arcmin, and its maximum
dimension is 2.65 deg (the minimum one is 7 arcmin).
The Sun distance was 97 deg.
This box may be improved.
A triangulation map is posted at

The time history and spectrum will be given in a forthcoming GCN Circular.
