Oct. 17, 2022: Astronomers have never seen anything quite like it. On Oct. 9, 2022, Earth-orbiting satellites detected the strongest gamma-ray burst (GRB) in modern history: GRB221009A. How strong was it? It caused electrical currents to flow through the surface of our planet. Dr. Andrew Klekociuk in Tasmania recorded the effect using an Earth Probe Antenna:

Note: Data from STIX have been flipped (increasing counts go down) to ease comparison of the two waveforms. NWC is a VLF transmitter in Australia.

The blue curve is a signal from Klekociuk’s antenna, which was sensing VLF (very low frequency) currents in the soil at the time of the blast. The orange curve shows the gamma-ray burst recorded by the high-energy STIX telescope on Europe’s Solar Orbiter spacecraft, one of many spacecraft that detected the event. The waveforms are a nearly perfect match.
