the Swift-BAT team, report:

GRB 110802A, a short-duration, hard spectrum burst, was detected by
Konus-Wind, MESSENGER GRNS, Odyssey HEND, Swift BAT (outside the coded
field of view), and Suzaku WAM at 55157 s UT.  We have triangulated it to
a preliminary 3 sigma error box whose area is 55 sq. arcmin. and whose
coordinates are

CENTER:  RA=44.455 o =  02h57m49s , DEC= +32.593 o = 32 o 35' 34"
CORNERS:    44.448 o=   02h57m48s        +32.932 o = 32 o 55' 54"
            44.476 o =  02h57m54s        +32.851 o = 32 o 51' 03"
            44.436 o =  02h57m45s        +32.329 o = 32 o 19' 45"
            44.465 o =  02h57m51s        +32.244 o = 32 o 14' 40"

Some improvement to this error box is possible.

A Swift ToO has been requested.  The spectrum and time history will
be reported in a forthcoming GCN Circular.
