and

E. Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team,
report:

The long-duration GRB 241130A
(Fermi-GBM detection: The Fermi GBM team, GCN 38405, 
Sharma et al., GCN 38421;
EIRSAT-1 GMOD Detection: McDermott et al., GCN 38423)
was detected by Fermi (GBM trigger 754701230), Konus-Wind,
INTEGRAL (SPI-ACS), and EIRSAT-1 (GMOD) at about 83625 s UT (23:13:45).

We have triangulated it to a preliminary, 3 sigma error box
whose coordinates are:
 ---------------------------------------------
  RA(2000), deg                 Dec(2000), deg
 ---------------------------------------------
 Center:
  111.465 (07h 25m 52s) -31.442 (-31d 26' 30")
 Corners:
  120.603 (08h 02m 25s) -25.812 (-25d 48' 42")
  122.268 (08h 09m 04s) -26.450 (-26d 27' 01")
   99.058 (06h 36m 14s) -35.673 (-35d 40' 23")
   96.603 (06h 26m 25s) -34.608 (-34d 36' 30")
 ---------------------------------------------
The error box area is 31 sq. deg, and its maximum
dimension is 23.5 deg (the minimum one is 1.4 deg).
The Sun distance was 108 deg.

The IPN localization is consistent with, but reduces the area of,
the Fermi-GBM localization (GCN 38405).

This localization may be improved.

A triangulation map and HEALPix FITS file are posted at
http://www.ioffe.ru/LEA/GRBs/GRB241130_T83628/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.
