SUBJECT: GRB 231003A: Fermi GBM Final Real-time Localization
DATE: 23/10/03 21:12:36 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 21:01:59 UT on 3 Oct 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231003A (trigger 718059724.905152 / 231003876).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 300.8, Dec = 71.1 (J2000 degrees, equivalent to J2000 20h 03m, 71d 05'), with a statistical uncertainty of 1.4 degrees.
The angle from the Fermi LAT boresight is 169.0 degrees.

SUBJECT: GRB 231003A is not a GRB
DATE: 23/10/04 02:17:22 GMT
FROM: Cori Fletcher at USRA
C. Fletcher (USRA) reports on behalf of the Fermi Gamma-ray Burst Monitor Team:
"The Fermi Gamma-ray Burst Monitor (GBM) trigger 718059724/231003876 at 21:01:59.91 UT on 03 October 2023, tentatively classified as GRB 231003A (GCN34793), is in fact not due to a GRB. This trigger is likely due to local particles." |
