The short-duration GRB 240514B
(Fermi-GBM detection: The Fermi GBM team, GCN 36469Not found
 
 
;
Roberts and Meegan, GCN 36481Not found
 
 
;
GRBAlpha detection: Ripa et al., GCN 36484Not found
 
 
)
was detected by Fermi (GBM trigger 737352230), Swift (BAT),
INTEGRAL (SPI-ACS), GRBAlpha, and Konus-Wind, in the waiting mode,
at about 14625 s UT (04:03:45).
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:
  77.510  (05h 10m 02s) +53.570 (+53o 34' 12")
 Corners:
  147.796 (09h 51m 11s) +57.777 (+57d 46' 37")
    7.396 (00h 29m 35s) +57.580 (+57d 34' 49")
    7.207 (00h 28m 50s) +47.865 (+47d 51' 55")
  148.019 (09h 52m 04s) +48.062 (+48d 03' 43")
 ---------------------------------------------
The error box area is 816 sq. deg, and its maximum
dimension is 69 deg (the minimum one is 9.7 deg).
The Sun distance was 46 deg.

This localization may be improved.

The optical transient reported by Kumar et al., GCN 36488Not found
 
 
 is outside the IPN error box and the updated Fermi-GBM localization (glg_healpix_all_bn240514169_v02).
