What effect did storms on the sun have on the earth and compass needles?

Storms on the Sun, known as solar storms or solar flares, can have various effects on the Earth and compass needles. Here are a few effects:

1. Auroras: Intense solar storms can cause powerful geomagnetic disturbances on Earth. These disturbances can create stunning displays of light in the sky called auroras, commonly known as the Northern Lights (aurora borealis) in the northern hemisphere and Southern Lights (aurora australis) in the southern hemisphere. Auroras occur when charged particles from the solar storm interact with the Earth's magnetic field and atmosphere.

2. Radio Interference: Solar storms can release a burst of electromagnetic radiation, including X-rays and radio waves, which can interfere with radio communication, satellite signals, and GPS navigation systems. This interference can affect communication, navigation, and other technological systems that rely on these signals.

3. Power Grid Disruptions: Solar storms can induce strong electric currents in long conductors like power lines. In extreme cases, these induced currents can cause disruptions and damages to power grids, leading to blackouts or power outages.

4. Compass Deviation: Magnetic storms caused by solar flares can cause slight temporary disturbances in Earth's magnetic field. These disturbances can affect the accuracy of compass readings, making compass needles deviate from their true north orientation. However, these effects are usually minimal and temporary.

It's important to note that while solar storms can have such effects, their impact on the Earth and compass needles depends on various factors such as the intensity and direction of the storm's magnetic field, as well as the geographical location of the observer.
