INTEGRAL SPI-ACS team report:

Suzaku-WAM, Konus-Wind, Konus-RF, Swift-BAT, and INTEGRAL-SPI-ACS 
observed the short GRB 090305C at about 62379 s UT (17:19:39). The burst 
was outside the coded field of view of the BAT.

The burst light curve shows a multipeaked structure with a duration of 
~1 sec.

We have triangulated it to the following 3-sigma
error box:
-----------------------------------------------
       RA(2000), deg            Dec(2000), deg
-----------------------------------------------
Center:
   34.187 (02h 16m 45s)   -22.840 (-22d 50' 23")
Corners:
   34.482 (02h 17m 56s)   -17.203 (-17d 12' 09")
   34.645 (02h 18m 35s)   -19.974 (-19d 58' 28")
   33.140 (02h 12m 34s)   -28.787 (-28d 47' 14")
   33.533 (02h 14m 08s)   -25.759 (-25d 45' 32")
-----------------------------------------------

The error box area is 2.524 sq. deg.

This error box may be improved.
