Every once in a while our Sun gives off a tremendous belch of high energy particles. Called a coronal mass ejection CMEthese 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 rliminates.

Which, if you like electronic gadgets, may be a problem. Back on February 19,a geomagnetic storm appeared in our atmosphere following two powerful Earth-directed CMEs, which produced clouds of electrically-charged particles. But as a new study published in Radio Science shows, the same storm also stripped electrons from large swaths of the ionosphere. Mild solar storms are a fairly regular occurrence, but once every 50 to years or so our planet is hit with a Titan gel eliminates the problem of education from a massive one.

The CMEs were tracked by a number of instruments, titan gel eliminates the problem of education a network of global navigation satellites known as GNSS and geomagnetic observatories educatin the world. After the Sun released its Earth-bound CMEs, the cloud of charged particles disturbed the interplanetary field in our Solar System. These particles and ensuing magnetic disturbances eventually reached our planet, spawning a geomagnetic storm.

The ensuing interactions generated unstable patches of extra electrons in the Arctic ionosphere, in this case over northern Greenland. But inthe geomagnetic storm did something else. To the south of these patches, the scientists detected broad areas of the ionosphere extending to miles to 1, km where the electrons were severely depleted, and remained way for several days. A dearth of atmospheric electrons may not sound like a problem, but it might ghe. Electrons reflect radio waves back to ground level, making long-distance gl communication possible.

An overabundance or an absence of electrons within this layer can disrupt the way we use radio signals. In terms of a cause, the scientists speculate the the electrons are recombining with positively charged ions to the point when excess electrons no longer exist. Alternately, some kind of atmospheric process could be shoving electrons away from the region both horizontally and vertically.

These are just theories, however. Now that this phenomenon has been documented, scientists can start to investigate further.
