Solar Flares

From Elite Wiki

A simple OXP that adds some flavour to systems that have "solar activity". The corona flare value of the sun occasionally increases, and then returns back to normal after a short period of time.

It's worth noting that should a flare occur whilst scooping fuel, you could be in trouble. Always have a jump preset! Even with the temperature on purple, you can survive if you jump out immediately, as your ship will cool down fast in Witchspace.

Solar Flare (coronal mass ejection)

A solar flare is a sudden flash of increased brightness on the Sun, usually observed near its surface and in close proximity to a sunspot group. Powerful flares are often, but not always, accompanied by a coronal mass ejection. Even the most powerful flares are barely detectable in the total solar irradiance (the "solar constant").

Solar flares occur in a power-law spectrum of magnitudes; an energy release of typically 1020 joules of energy suffices to produce a clearly observable event, while a major event can emit up to 1025 joules.

Flares are closely associated with the ejection of plasmas and particles through the Sun's corona into outer space; flares also copiously emit radio waves. If the ejection is in the direction of the Earth, particles associated with this disturbance can penetrate into the upper atmosphere (the ionosphere) and cause bright auroras, and may even disrupt long range radio communication. It usually takes days for the solar plasma ejecta to reach Earth. Flares also occur on other stars, where the term stellar flare applies. High-energy particles, which may be relativistic, can arrive almost simultaneously with the electromagnetic radiations.

Version History


  • System corona hue and flare values should now be restored correctly after a save game, so when the system is left no changes will be stored.


  • Initial release.

To remove Solar Flares

These were intensified back with Oolite v.1.80 in 2014.


Other OXP's

  • Distant Stars & Sun Gear (Strangers World suite) also introduce Solar Flares which are dependent on the sun type.
