and A.S. Gardner on on behalf of the GRS-Odyssey GRB team,
report:

The long-duration GRB 220613A
was detected by Konus-Wind, Mars-Odyssey (HEND),
BepiColombo (MGNS), and GECAM-B (trigger tn220613_202337_fb)
at about 73416 s UT (20:23:36).

We have triangulated it to a preliminary, 3 sigma error box
whose coordinates are:
 ---------------------------------------------
  RA(2000), deg                 Dec(2000), deg
 ---------------------------------------------
 Center:
  189.085 (12h 36m 20s) +14.022 (+14d 01' 21")
 Corners:
  188.733 (12h 34m 56s) +13.688 (+13d 41' 15")
  189.094 (12h 36m 22s) +14.268 (+14d 16' 06")
  189.435 (12h 37m 44s) +14.347 (+14d 20' 49")
  189.077 (12h 36m 19s) +13.776 (+13d 46' 35")
 ---------------------------------------------
The error box area is 584 sq. arcmin, and its maximum
dimension is 57 arcmin (the minimum one is 14.5 arcmin).
The Sun distance was 99 deg.

This box may be improved.

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