GRB 110808B, a very intense short-duration, hard spectrum GRB,
was observed by Konus-Wind, Mars Odyssey, MESSENGER, and RHESSI at
56693 s UT. We have triangulated it to a preliminary, 3 sigma error
box whose area is about 108 square arcminutes, whose maximum dimension
is ~22 arcminutes, and whose coordinates are:
CENTER: 266.1808=17 h 44 m 43.4 s -37.7463=-37 o 44 ' 47 "
CORNERS: 266.0492=17 h 44 m 11.8 s -37.7586=-37 o 45 ' 31 "
266.3453=17 h 45 m 22.9 s -37.8732=-37 o 52 ' 24 "
266.0166=17 h 44 m 04.0 s -37.6169=-37 o 37 ' 01 "
266.3123=17 h 45 m 14.9 s -37.7332=-37 o 44 ' 00 "
Although this error box lies at Galactic latitude -5 degrees, it does
not include any of the known magnetars. A Swift ToO has been requested.
Further details of the spectrum and time history will appear in a
forthcoming GCN Circular. A map is posted at
ssl.berkeley.edu/ipn3/110808B. This error box can be improved.
