[3] 230307A is the second brightest gamma ray burst detected in more than 50 years of observations and is located behind the Magellanic Bridge.

Despite its long duration, it is most likely the result of the compact merger of a binary ejected from a galaxy in the local universe (redshift z=0.065).

[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 time), Spectrometer Telescope for Imaging X-rays (STIX) detected GRB 230307A.

[10][11] Tellurium (Te) in GRB 230307A was discovered in 2023 by using the James Webb's Space Telescope's (JWST) mid infrared data.
