What it means
The sun throws off bursts of charged particles, and when one strikes Earth's magnetic field it induces currents in long conductors on the ground. A storm in 1989 collapsed the power grid across Quebec in under two minutes. A far larger event in 1859 set telegraph offices on fire and made auroras visible near the tropics, and something on that scale today would be considerably more expensive.
