SOLAR SYSTEM

Detailed explanation-1: -Space weather-caused by solar activity such as solar flares and coronal mass ejections-can impact the space between here and the sun and cause an aurora as a byproduct. Auroras can also be triggered by much less energetic events that lead to active conditions, such as fast solar wind streams from coronal holes.

Detailed explanation-2: -The radiation from that flare traveled at the speed of light to reach Earth in under ten minutes and disrupt communications for mariners, hams and other radio operators for almost an hour. But it’s what came next that’s bringing the aurora: an at-least partially earth-directed coronal mass ejection (CME).

Detailed explanation-3: -The x-rays from flares are stopped by our atmosphere well above the Earth’s surface. They do disturb the Earth’s ionosphere, however, which in turn disturbs radio communications. Along with energetic ultraviolet radiation, they heat the Earth’s outer atmosphere, causing it to expand.

Detailed explanation-4: -The magnetic field lines near sunspots often tangle, cross, and reorganize. This can cause a sudden explosion of energy called a solar flare. Solar flares release a lot of radiation into space. If a solar flare is very intense, the radiation it releases can interfere with our radio communications here on Earth.

Detailed explanation-5: -After the eruption of a solar flare, post-eruption loops made up of hot plasma begin to form across the neutral line separating regions of opposite magnetic polarity near the flare’s source.
