A very common form of 'space weather' phenomenon which affects spacecraft, stations, and planets in range of the flare.
Throughout space, various forms of 'space weather' manifest and take shape. Among these are Solar Storms - A sudden flash of electrons, ions, and atoms through a star's corona and into outer space., typically coupled with electromagnetic radiation. The rarity or commonality of these storms can vary from star to star, from almost non-existent to a regular event.
Due to the vast variety of appearances of stars themselves, Solar Storms can also vary widely in appearance. Typically, storms that are visible manifest in the same colors as their parent star and at a much higher level of brightness at their source, though most storms emit energy outside of the visible spectrum and can only be detected using special instruments. Solar Storms can have a variety of effects on planets, ships, and stations. Most notable are the creation of radiation and electromagnetic hazards which can damage or disable stations, satellites, and ships, or cause severe radiation sickness among crews - Even those that are shielded from such events if the storm is powerful enough. Some storms are also able to penetrate planetary magnetospheres, disrupting electrical systems.
While the rarity of Solar Storms can vary, every Solar Storm in the galaxy eminates from an existing star. Because of this such storms are typically only ever seen within or near star systems before the energy is dispersed to negligible levels, with the void between systems only showing traces of the strongest solar storms.
