At 14:49:45.666 GRB 110604A triggered Konus-Wind.  The Interplanetary
Network was alerted.  The burst was also detected by Swift-BAT,
MESSENGER (GRNS), Suzaku WAM, and INTEGRAL SPI-ACS.  Triangulation
yielded overlapping annuli that partly intersected the BAT field of
view.  A sub-threshold peak on the edge of the corresponding BAT image
was consistent with the annuli.  The BAT location is
RA, Dec 271.003, +18.472 or

RA (J2000)     18h 04m 00.7s
Dec (J2000)    18d 28' 19.2"

with an estimated uncertainty of 5 arcmin radius.

The burst was about 30 seconds long with 4 separated peaks.  The usual
detailed BAT products will not be available for this burst, since the
coding was only about 0.2%.

A Swift TOO request has been approved.
