Solar flares are directed to Earth


The cloud of charged particles could affect today and satellite navigation and electric power. The largest solar storm in five years is about to shake the Earth's magnetic field.
After going through the day and a half space, a huge cloud of charged particles arrive today and could affect electricity networks, satellite navigation systems and flight of aircraft, especially in regions of the northern hemisphere.
However, the same storm may produce colorful auroras at the poles further away than usual.Scientists said on Wednesday that the storm, which began with a huge solar flare earlier this week, is growing as it moves away from the Sun, rising like a huge soap bubble.

Astronauts are those most exposed to storms that occur in space


NASA carefully monitors the radiation dose accumulated by each astronaut throughout his career. Every release, every spacewalk solar flare and all are taken into account carefully. If an astronaut gets too close to the limit, you may not be allowed to leave the space station! The accurate warnings about the weather in space could be kept under control exposure to radiation, postponing spacewalks, for example, when there is a likelihood of occurrence of a rash
In his presentation at the forum, Allen proposed to establish a new type of forecast. "It could be useful alerts from All Clear. Besides knowing when it is too dangerous to leave, we would like to know also when it is safe. This is another challenge for forecasters: not only will tell us when a sunspot eruption, but also when no the will.

The emergence of models of space weather


They manage to do this using the data collected by the fleet of spacecraft that NASA has in orbit around the Sun laboratory analysts provide information to a group of supercomputers which is responsible for processing. A few hours after an eruption of great magnitude, computers produce a three dimensional film shows where the storm goes and what planets and spacecraft will be hit, also predicts the film will occur when each impact. This type of prediction of interplanetary weather is unprecedented in the short history of weather forecasting in space."This is an exciting time to work as a forecaster of space weather," says Ante Pulkkinen, who is a researcher at the Laboratory of Space Weather. "The emergence of models of space weather based on serious physical is giving us the ability to predict if and when a major event."
