The long-duration GRB 171102A (Yassine et al., GCN Circ. 22081Not found
 
 
; Stanbro 
et al., GCN Circ. 22083Not found
 
 
) was detected by Konus-Wind, Fermi (GBM trigger 
531282820), INTEGRAL (SPI-ACS), and Swift (BAT) at about 9216 s UT 
(02:33:36). 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:
   188.823 (12h 35m 18s) +54.288 (+54d 17' 15")
  Corners:
   180.299 (12h 01m 12s) +53.175 (+53d 10' 31")
   179.157 (11h 56m 38s) +54.095 (+54d 05' 41")
   197.995 (13h 11m 59s) +54.514 (+54d 30' 52")
   198.922 (13h 15m 41s) +53.378 (+53d 22' 41")
  ---------------------------------------------
The error box area is 11.5 sq. deg, and its maximum
dimension is 11.7 deg (the minimum one is ~1 deg).
The Sun distance was about 70 deg.

This box may be improved.
