SUBJECT: GRB 250214A: Fermi GBM Final Real-time Localization
DATE: 25/02/14 05:42:39 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 05:32:07 UT on 14 Feb 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250214A (trigger 761203932.174936 / 250214231).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 122.8, Dec = -41.9 (J2000 degrees, equivalent to J2000 08h 11m, -41d 53'), with a statistical uncertainty of 5.3 degrees.
The angle from the Fermi LAT boresight is 122.0 degrees.

SVOM/GRM team: Chao Zheng, Shi-Jie Zheng, Shao-Lin Xiong, Yue Huang, Shuang-Nan Zhang (IHEP)
SVOM/ECLAIRs team: Frédéric Piron (LUPM), Nicolas Dagoneau (CEA), Maria-Grazia Bernardini (INAF-OAB), Jean-Luc Atteia (IRAP) report on behalf of the SVOM team:
SVOM/GRM detected GRB 250214A at 2025-02-14T05:32:06 UT (T0), which was also observed by Fermi/GBM (Fermi GBM team, GCN #39320).
With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of multi-pulses with a duration of about 6 seconds in the 15-600 keV band.

The Space Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA, China), National Center for Space Studies (CNES, France) and the Chinese Academy of Sciences (CAS, China), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. GRM is developed by the Institute of High Energy Physics (IHEP) of CAS.
