The MASTER-Kislovodsk robotic telescope in Russia initiated observations of Fermi GRB 260314A 83 seconds after the trigger time, reporting upper limits on magnitudes ranging from 17.8 to 18.8 in clear band for various observation times. The galactic coordinates of the GRB are b = 34 deg., l = 92 deg.
GCN-43997 — GRB 260314A
· Sat, 14 Mar 2026 01:09:31 GMT
The Fermi Gamma-ray Burst Monitor (GBM) has detected and located a new long gamma-ray burst (GRB 260314A) at coordinates RA = 260.2, Dec = 62.9 (J2000), with a statistical uncertainty of 8.2 degrees. The angle from the Fermi Large Area Telescope (LAT) boresight is 59.0 degrees. This event is significant as gamma-ray bursts are among the most energetic phenomena in the universe and provide valuable insights into astrophysical processes.
