When strong solar storms are diverted poleward by our magnetic fields we often observe in the ionosphere?

When strong solar storms are diverted poleward by Earth's magnetic fields, they can lead to the formation of auroras, commonly known as the Northern and Southern Lights. This occurs as charged particles from the solar wind interact with the ionosphere, exciting gas molecules and causing them to emit light. Additionally, these storms can disrupt radio communications and GPS signals, as well as affect satellites and power grids on Earth. The resulting ionospheric disturbances can lead to increased ionization and variability in the upper atmosphere.
