The gamma-ray burst was ten minutes long, [1] but was detectable for more than ten hours following initial detection. [2] [3] Despite being around 2.4 billion light-years away, it was powerful enough to affect Earth's atmosphere, having the strongest effect ever recorded by a gamma-ray burst on the planet.
It is the most energetic gamma-ray burst ever recorded. It has been deemed to be the "B.O.A.T.", or Brightest Of All Time. It had the highest fluence and peak flux ever identified, by a large margin. [14] It also holds the record for highest energy burst recorded if released isotropically, beating GRB 080916C. [14]
At 15:44:06 UT on 7 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230307A . [6] at the same time, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor light curve shows a roughly fast rise and exponential decay (FRED) shape with a possible precursor, with a total duration of ~100 sec. [7] At 2023-03-07T15:44:09Z UT (Solar Orbiter onboard ...
The gamma-ray burst occurred two billion light-years away from Earth. Cosmic explosion that blinded space instruments ‘may be the brightest ever seen’ Skip to main content
The brightest gamma ray burst ever detected recently reached our planet. It’s 70 times longer than any other burst we’ve spotted, and effectively blinded our instruments when it hit.

GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds. [3]
This gamma-ray burst, researchers said on Tuesday, caused a significant disturbance in Earth's ionosphere, a layer of the planet's upper atmosphere that contains electrically charge
