S. Golenetskii, R. Aptekar, V. Pal'shin, D. Frederiks, D. Svinkin, and
T. Cline, on behalf of the Konus-Wind team,
A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C.
Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, and
S. Barthelmy, J. Cummings, N. Gehrels, H. Krimm, and D. Palmer, on
behalf of the Swift-BAT team, report:
The long-duration very intense GRB 140320D has been observed by
Konus-Wind, INTEGRAL (SPI-ACS), Swift (BAT), and MESSENGER (GRNS), so
far, at about 73297 s UT (20:21:37). 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:
87.893 (05h 51m 34s) +85.429 (+85d 25' 46")
Corners:
98.997 (06h 35m 59s) +86.721 (+86d 43' 15")
98.219 (06h 32m 53s) +87.023 (+87d 01' 23")
81.849 (05h 27m 24s) +84.026 (+84d 01' 35")
83.033 (05h 32m 08s) +83.741 (+83d 44' 28")
---------------------------------------------
The error box area is 0.635 sq. deg, and its maximum dimension is 3.474
deg (the minimum one is 0.196 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.
