Solar flare

Solar flares are bursts of energy given off by active stars periodically. Solar flares contain gamma radiation which can be used as a power source and they can devastate entire planets.

Historical significance

 * The greatest solar flare for a thousand years hit the Earth in 1930 and, attracted by dalekanium, striked the Empire State Building.(DW: Evolution of the Daleks)


 * Because of this being the greatest solar flare for a thousand years, it can be assumed that another solar flare hit the Earth in 2930.


 * Sometime after the 31st century, Human scientists predicted that due to solar flare activity the Earth would be uninhabitable for 5000 years, and froze a group of carefully selected humans in an "Ark" in space to repopulate the Earth thereafter. The rest of the humans were evacuated to Thermic shelters but where apparently not expected to survive trough the entire period. (DW: The Ark in Space)


 * The Controller of the Game Station in 200,100 exploited a cycle of solar flares, which occured every eleven years, to warn the Doctor and his allies about a mysterious enemy. During this time her masters, the Daleks could not monitor her. (DW: Bad Wolf)
 * Circa 2,000,000 CE, the Time Lords transported the entire solar system using a magnetron. (DW: ''The Mysterious Planet).
 * In some unknown way, the move once more devastated Earth, which less informed people attributed to solar flares.
