Every once in a while our Sun gives off a tremendous belch of high energy particles. Called a coronal mass ejection (CME), these episodes can vary in intensity, but they can produce bursts of electrical charge when they interact with our upper atmosphere in a geomagnetic storm. In a strange twist, new research shows that geomagnetic storms can produce the opposite effect, stripping the upper atmosphere of electrons for hundreds of kilometres. Which, if you like electronic gadgets, may be a problem.
