6/🧵That's not enough radiation to cause a health emergency for passengers, but it was a concern for avionics. During the storm's peak, the researchers estimate that single-event upsets (bit-flips in computer memory) could have occurred at rates of ~60 errors per hour per gigabyte.

4/🧵The event began with an X5-class solar flare on Nov. 11th. Dyer and colleagues rapidly organized balloon launches with radiation sensors over the UK. They found effective dose rates at 40,000 feet exceeding 55 μSv per hour, with some flight paths possibly reaching 80 μSv per hour.

3/🧵"This was the strongest Ground Level Event (GLE) since Dec. 13, 2006," says Professor Clive Dyer of the Surrey Space Centre. "Neutron monitors around the world detected it."

2/🧵Our home planet is a delicate and unique jewel floating in the vacuum of space. Why our shared capitalist system, known as Neo-liberalism, treats it like a toilet will forever boggle my mind.
