SUBJECT: GRB 230712A: Fermi GBM Final Real-time Localization
DATE: 23/07/12 00:49:51 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 00:39:13 UT on 12 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230712A (trigger 710815158.21058 / 230712027).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 153.8, Dec = 28.5 (J2000 degrees, equivalent to J2000 10h 15m, 28d 30'), with a statistical uncertainty of 19.6 degrees.
The angle from the Fermi LAT boresight is 73.0 degrees.

S. Barthelmy, J. Cummings, H. Krimm, D. Palmer, and A. Tohuvavohu
on behalf of the Swift-BAT team, report:
The short-duration GRB 230712A
(Fermi-GBM detection: The Fermi GBM team, GCN Circ. 34204)
was detected by Fermi (GBM trigger 710815158) and
INTEGRAL (SPI-ACS) at about 81618 s UT (22:40:18).
We have triangulated it to a GBM-SPI-ACS annulus centered at
RA(2000)=216.150 deg (14h 24m 36s) Dec(2000)=+43.693 deg (+43d 41' 34")
whose radius is 74.146 +/- 8.027 deg (3 sigma).
The annulus combined with the Fermi-GBM final position (GCN 34204;
glg_healpix_all_bn230712027_v00) gives 1125 sq. deg (3 sigma) localization region.
