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

The long-duration GRB 190611B (Malacaria and Meegan, GCN Circ. 24794) 
was detected by Fermi (GBM), Konus-Wind, INTEGRAL (SPI-ACS),
Mars-Odyssey (HEND), and Swift (BAT) at about 82069 s UT (22:47:49).

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:
    84.968 (05h 39m 52s) +52.773 (+52d 46' 24")
  Corners:
    81.481 (05h 25m 55s) +50.833 (+50d 49' 57")
    88.130 (05h 52m 31s) +54.352 (+54d 21' 06")
    89.119 (05h 56m 29s) +54.477 (+54d 28' 38")
    82.284 (05h 29m 08s) +51.059 (+51d 03' 34")
  ---------------------------------------------
The error box area is about 1.15 sq. deg, and its maximum
dimension is 5.9 deg (the minimum one is 6.42 arcmin).
The Sun distance was about 30 deg.

This box may be improved.

The Konus-Wind time history and spectrum will be given in a forthcoming
GCN Circular.
