solar flare 2011:5 years, the outbreak of the strongest solar storms

NASA's Solar Dynamics Observatory satellite observations to 5 years the most violent solar flare eruption, reached the earth can cause moderate geomagnetic storms affect satellite communications and power supply on the planet. According to Solar Dynamics Observatory satellite observations, in addition to a small radiation storms, but the sun broke out accompanied by a flare and a coronal mass ejections.

 

The National Weather Service Space Weather Prediction Center Program Coordinator, Bill. Muta Fu said: "This time is very dramatic explosion." He pointed out that medium-sized solar flares in the 6 Eastern Time 1:41 (Greenwich Mean time 5:41) peak. "We first observed the flare size is not large, in the subsequent eruption, we observed high-energy particle radiation and large-scale coronal mass ejections. You can observe all ejected from the solar surface material, very spectacular sight. "

 

Solar Dynamics Observatory satellite launched in 2010, photographed the solar eruptions of high-definition photos and video. According to observation, the sun broke out visually spectacular, as not being on the planet, the impact on the Earth may be very small. NASA said in a statement: "a tremendous increase in mushroom cloud of particles, and then fall back to the surface of the sun, seems to cover almost half of the solar surface."

 

Muta Fu pointed out that space weather analysts are closely watching the sun broke out, to determine whether the cause between the Sun and the Earth's magnetic field collision. At the distance of about 150 million kilometers or so. In an interview with French media interview he said: "Part of our job is to monitor both the material to determine whether the outbreak of the sun, the earth flying, basically because of the gas jet and the material with a magnetic field. Within a day or two we will see some of the sun spray material impact on the Earth, the formation of a geomagnetic storm. We do not think this will be a very intense geomagnetic storm, but the strength can still reach the middle level. "

 

Space Weather Prediction Center said that the sun caused the outbreak in 8 small to medium-sized geomagnetic storms, from approximately 18:00 Greenwich Mean Time began. Any geomagnetic storm activity will end within 24 hours. National Weather Service, said: "There are a lot of solar radiation high-energy proton storm, this type of activity since December 2006 is the first time since the observed."

 

A total of 12 satellites and spacecraft to monitor the heliosphere, NASA Lunar Reconnaissance Orbiter will carry instruments to measure and analyze the radiation effects can be derived. The effects of radiation cosmic ray Telescope (CRaTER) project, said lead researcher Harran Spencer: "CRaTER task starts the past two years, which is observed most important events. This is an exciting moment. Ironically, is in the planning of this task, we initially thought that should be launched in the solar maximum, because the intense solar particle events often occur during this period. In fact, we are launching solar minimum, the sun takes a long time to wake up . This is an interesting and important moment because there are indications that the Sun is back on active status. "

 

Geomagnetic storms caused by solar eruptions on the planet will affect the number of power grids, satellite global positioning systems and other equipment, while flying over the polar regions will lead to forced to change their flights over the route. He said: "Under normal circumstances would not cause much destruction, threatening in the controllable range. If the passenger unit from the U.S. to Asia over the North Pole, you will find more than a dozen flights. Every day is like this . massive radiation storms, some airlines will allow flights for security reasons, change the route, away from the polar regions, to ensure flight to keep communication open. operating the satellite company will pay close attention, because the geomagnetic storm will be a variety of ways interfere with the satellite and the receiver receiving the signal. "NASA said that in the 8 pm and 9, the polar regions may also be observed in the northern lights and southern auroras.
