Coronal mass ejection
From SGCommand
A Coronal mass ejection is an ejection of plasma from the corona of a star.
[edit] History
The coronal mass ejection from the star of P4X-639 created a geomagnetic disturbance and was used in 2000 to activate the Ancient Time loop machine. (SG1: "Window of Opportunity")
The star in the Lantean system produces a larger coronal mass ejection than our own star. Every 15,000 years, the ejection of the star is large enough to devastate the planet Lantea. 15,000 years ago, the Lantean ship Adaris was hit by such an ejection. The radiation killed most of the crew, but the badly burned captain sent the ship through hyperspace to Atlantis to warn the Lanteans about the coronal mass ejection. The Lanteans used the three ZPMs of the city to expand the sheild to cover a significant portion of the planet, thus saving most of it. In 2006, the Atlantis expedition encountered another one after being telepathically warned by the Flagisallus. The expedition used their one ZPM to strengthen the Daedalus' shield and intercepted the coronal mass ejection, which luckily only lasted a short amount of time. (ATL: "Echoes")
