Extremely powerful gamma ray burst swept across Earth in early October

Amazing stuff! Did you notice anything? Any health implications (they claim it is harmless)?

"The signal, designated GRB 221009A, was detected on October 9 – although the explosion itself occurred 1.9 billion years ago. It came from the direction of the constellation Sagitta, and was visible to telescopes for more than 10 hours, making it one of the longest-lasting GRBs detected. ...
GRB 221009A was found to deliver the highest energy of any GRB ever detected. The energy of these events is usually measured in giga-electronvolts (GeV), but a few have been recorded with energies of about 1 tera-electronvolt (TeV). But this new event may have reached a record-breaking 18 TeV, marking the first detection of a GRB with energies above 10 TeV. ...
While 1.9 billion light-years may not sound very close, most others are detected several billion light-years or more away. This proximity also explains why it glowed for so much longer afterwards. ...
It’s worth noting that despite its intensity and proximity, this GRB is harmless to Earth. ..."

"Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB) – the most powerful class of explosions in the universe – that ranks among the most luminous events known. ..."

Extremely powerful gamma ray burst sweeps across Earth Gamma ray bursts (GRBs) are among the most energetic explosions since the Big Bang – and now astronomers have detected the most powerful one yet. A beam of high-energy radiation up to 18 times more powerful than the previous record swept over Earth last weekend [10/8-10/9/2022].
