INTEGRAL SPI-ACS GRB team, report:
This burst (GCN 2487, 2488) was also observed by Mars Odyssey (GRS) and
INTEGRAL (SPI-ACS). As observed by Wind and Helicon, it had a 15-8000
keV fluence of approximately 3.4E-04 erg/cm2, and a peak flux of
approximately 2E-03 erg/cm2 s over 0.004 seconds. This event had a
hard spectrum with Epeak = 2000 +/- 80 keV. As reported in GCN 2487
and 2488, it had a duration of ~0.3 s, which places this GRB in the
short/hard class.
We have triangulated it to a preliminary, 3 sigma error box whose
area is ~70 sq. arcmin. and whose coordinates are:
RA(2000) Dec(2000)
245.525 -11.207
245.478 -11.300
245.471 -11.715
245.423 -11.817
This error box may be improved.

Very bright short GRB031214 was detected by Konus-Wind at 36655.479 UT
(10:10:55.479) and by Helicon-Coronas-F at 36650.711 UT (10:10:50.711).
It has a duration of ~0.3 sec.
We have triangulated it to a preliminary annulus centered at
RA(2000) = 264.185 deg,
Decl(2000) = -19.141 deg,
Radius = 19.608 +/- 0.084 degrees (3 sigma ).
