Gammaglimt GRB-221009A ramte jorden 9. oktober 2022 - virkning på radiobølger?

Den 9. oktober 2022 blev jordens atmosfære ramt at et meget kraftigt gammaglimt over næsten 10 minutter. Var der nogen som mærkede virkningen på radio - fx HF?

Tid: Start omkring “2022-10-09 13:20...22 UT“ (VLF alarm), “2022-10-09 13:16:59.000 UT“ eller “12216 sec after trigger time at 2022-10-09 17:33:54 UT“. ?

27 oktober 2022, Gammaglimt har påvirket Jorden over en afstand på 2,4 milliarder lysår.
Gammaglimtet GRB 221009A, der overbelastede instrumentbrættet på adskillige satellitter, har allerede fået tilnavnet BOAT - Brightest of All Time.

Citat: “...
Men det var, hvad astronomerne målte 9. oktober: Et gammaglimt, som ioniserede den øvre atmosfære og derved kom til at påvirke den kommunikation, som anvender radiobølger med stor bølgelængde.
...
Gammaglimtet GRB 221009A var så voldsomt, at det allerede har fået sit eget navn: BOAT.
Det står for ’Brightetst of All Time’. Glimtet overbelastede instrumenterne på flere satellitter, og man kunne måle gammastrålingen i næsten 10 minutter, hvilket er helt usædvanligt for et gammaglimt.
Energien af fotonerne i gammaglimtet var op til 18 TeV (Teraelektronvolt).

Citat: “...
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.

“I am a climate scientist at the Australian Antarctic Division–that’s my day job,” says Klekociuk. “VLF is my hobby. I started doing VLF radio measurements in the 1970’s when I was in high school. This is the first time I have detected a gamma-ray burst.”

Klekociuk’s unusual “ham rig” uses Earth itself as a giant antenna. In his back garden there are two metal spikes stuck into the ground 75 meters apart. They are connected to a radio receiver via insulated buried wires. In recent years amateur radio operators have been experimenting with this weird kind of antenna to detect VLF radio signals circling our planet in the Earth-ionosphere waveguide. Earth’s crust forms one of the waveguide’s walls, allowing Earth Probe antennas to detect distant transmitters.

“During the gamma-ray burst I detected flickering from multiple stations,” says Klekociuk, who made this map showing transmission paths illuminated by the GRB:

Det var da noget af en begivenhed..:-)

Jeg hørte det ikke, men jeg hørte da Jupiter i sine tider blev ramt af meteoren, det gav et vældigt skrald på 21 mhz som blev optaget og dokumenteret over hele planeten.

INTET som helst at se på min Geiger tæller der altid står og laver live kurver, så der var intet i det radioaktive at måle.

Svar til #3:

En geigertæller eller Geiger-Müllertæller kan ikke detektere gammastråling.

Geiger-Müller-rør:

GM-rør er følsomme over for alfa-, beta- og gammastråling. De leveres med en beskyttelseshætte for det sarte glimmervindue (fjernes ved måling på f.eks. alfastråling).

Svar til #6:

Du har da helt ret. Jeg tænkte på neutronstråling, som jo ikke er helt det samme ;-) hehe.
