The long-duration GRB 241114B
(Insight-HXMT-HE detection: Wang et al., GCN 38284Loading...
 
 )
was detected by Konus-Wind, INTEGRAL (SPI-ACS), Swift (BAT),
NuSTAR (AC), and Insight-HXMT (HE) at about 39904 s UT (11:05:04).
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:
  304.514 (20h 18m 03s) -10.028 (-10d 01' 40")
 Corners:
  302.298 (20h 09m 12s)  -7.588 ( -7d 35' 17")
  303.748 (20h 15m 00s)  -7.242 ( -7d 14' 31")
  306.603 (20h 26m 25s) -12.501 (-12d 30' 04")
  305.164 (20h 20m 39s) -12.843 (-12d 50' 34")
 ---------------------------------------------
The error box area is 8.4 sq. deg, and its maximum
dimension is 6.5 deg (the minimum one is 1.4 deg).
The Sun distance was 70 deg.

This localization may be improved.

A triangulation map and HEALPix FITS file are posted at
http://www.ioffe.ru/LEA/GRBs/GRB241114_T39903/IPN
The HEALPix triangulation map is the multi-order HEALPix in units of
probability density.

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