and

W. Boynton, C. Fellows, K. Harshman, H. Enos, and R. Starr,
on behalf of the GRS-Odyssey GRB team, report:

The long-duration GRB 180605A was detected by
Fermi (GBM; trigger 549889170), INTEGRAL (SPI-ACS), Konus-Wind,
and Mars-Odyssey (HEND), at about 39565 s UT (10:59:25).

We have triangulated it to a preliminary, 3 sigma error box
whose coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
    47.510 (03h 10m 02s) -48.025 (-48d 01' 30")
  Corners:
    47.466 (03h 09m 52s) -48.645 (-48d 38' 43")
    48.461 (03h 13m 51s) -48.996 (-48d 59' 45")
    47.551 (03h 10m 12s) -47.403 (-47d 24' 11")
    46.582 (03h 06m 20s) -47.035 (-47d 02' 07")
  ---------------------------------------------
The error box area is 3009 sq. arcmin, and its maximum
dimension is 2.33 deg (the minimum one is 29.28 arcmin).
The Sun distance was 73 deg.

This box may be improved.

The time history and spectrum will be given in forthcoming
GCN Circulars.
