· Tue, 10 Feb 2026 18:24:59 GMT
The Fermi Gamma-ray Burst Monitor (GBM) has detected and localized a gamma-ray burst (GRB 260210B) at a preliminary position RA = 6.0, Dec = -48.3, with a statistical uncertainty of 10.3 degrees. The angle from the Fermi Large Area Telescope (LAT) boresight is 22.0 degrees. This event is significant as gamma-ray bursts are among the most powerful explosions in the universe and provide valuable insights into the nature of the most extreme phenomena in the cosmos.
