on behalf of the Swift-BAT team, report:

The short-duration GRB 160612A (Burns et al., GCN Circ. 19531) has been
detected by Fermi (GBM), Konus-Wind, INTEGRAL (SPI-ACS), and Swift (BAT),
so far, at about 72768 s UT (20:12:48). The burst was outside the coded
field of view of the BAT.

We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
 ---------------------------------------------
  RA(2000), deg                 Dec(2000), deg
 ---------------------------------------------
 Center:
  348.342 (23h 13m 22s) -25.181 (-25d 10' 51")
 Corners:
  348.982 (23h 15m 56s) -27.398 (-27d 23' 52")
  349.501 (23h 18m 00s) -27.279 (-27d 16' 45")
  347.719 (23h 10m 52s) -22.963 (-22d 57' 45")
  347.216 (23h 08m 52s) -23.074 (-23d 04' 27")
 ---------------------------------------------
The error box area is 2.18 sq. deg, and its maximum
dimension is 4.7 deg (the minimum one is 28 arcmin).
The Sun distance was about 102 deg.

This box may be improved.
