A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team, report:

Mars Odyssey (GRS), Konus-Wind, MESSENGER (GRNS), Suzaku-WAM,
Swift-BAT, AGILE-MCAL, and INTEGRAL SPI-ACS observed the long-duration
GRB 080122 at about 66764 s UT (18:32:44).  The burst was outside the
coded field of view of the BAT. The time history consists of several
multipeaked pulses with a total duration of ~150 sec.

We have triangulated it to the following, preliminary 3-sigma 
error box:
-----------------------------------------------
     RA(2000), deg            Dec(2000), deg
-----------------------------------------------
Center:
  191.352 (12h 45m 24s)   +27.014 (+27d 00' 49")
Corners:
  191.825 (12h 47m 18s)   +27.508 (+27d 30' 30")
  191.786 (12h 47m 09s)   +27.830 (+27d 49' 47")
  190.880 (12h 43m 31s)   +26.512 (+26d 30' 44")
  190.914 (12h 43m 39s)   +26.181 (+26d 10' 52")
-----------------------------------------------

The error box area is 1106 sq. arcmin.  Some improvement
is possible.

Preliminary analysis of the Konus-Wind data yields
a burst fluence of ~5x10^-5 erg/cm2 (in the 20 keV - 1 MeV range),
and an Epeak of the time-integrated spectrum of ~260 keV.

Detailed spectral parameters will be reported later.
