Ejeção de massa coronal visto pelo Observatório de Dinâmica Solar 7 de junho de 2011
The Sun unleashed an M-2 (medium-sized) solar flare, an S1-class (minor) radiation storm and a spectacular coronal mass ejection (CME) on June 7, 2011 from sunspot complex 1226-1227. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface.
O Sol desencadeou uma M-2 (médias empresas) explosão solar, umatempestade de radiação S1-classe (menor) e uma ejeção de massa espetacular coronal (CME), em 07 de junho de 2011 a partirdas manchas solares complexas 1226-1227. A grande nuvem departículas multiplicaram-se e caiu de volta olhando como se cobriuuma área de quase metade da superfície solar.

O Solar Dynamics Observatory (SDO) observaram o pico do surtoem 01:41 ET (0641 UT). SDO gravou essas imagens (acima) emluz ultravioleta extrema que mostram uma erupção muito grande degás frio. É algo único, pois em muitos lugares na erupção parece haver material ainda mais espetacular - a temperaturas inferiores a80.000 K.
The Solar Dynamics Observatory (SDO) observed the flare's peak at 1:41a.m. ET (0641 UT). SDO recorded these images (above) in extreme ultraviolet light that show a very large eruption of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material -- at temperatures less than 80,000 K.
All of the solar Heliophysics System Observatory missions captured the event.

Quando visto no Observatório Solar e Heliosférico's (SOHO)coronagraphs (canto superior direito), o evento mostra plasmabrilhante e partículas de alta energia que ruge do sol.
Também para a direita estão os links para o Solar TerrestrialRelations Observatory (STEREO) à frente e atrás coronographvídeos mostrando a expansão CME visto de cada lado do sol. Osatélite STEREO Ahead precede a Terra como ela circula o sol.O satélite STEREO Atrás segue atrás da Terra em sua órbita do sol. (NOTA: Ambos os vídeos estéreo será substituído pela versãode melhor qualidade quando eles se tornam disponíveis em 48 horas.)
Esta CME não-quadrado da Terra está se movendo dirigido a 1400 km / s de acordo com modelos da NASA. O CME deveentregar um sopro de olhar para o campo magnético da Terradurante as últimas horas de 08 de junho ou 09 de junho.Observadores do céu alta latitude devem estar alertas para as auroras quando o CME chega.
When viewed in Solar and Heliospheric Observatory's (SOHO) coronagraphs (top right), the event shows bright plasma and high-energy particles roaring from the Sun.
Also to the right are links to the Solar Terrestrial Relations Observatory (STEREO) Ahead and Behind coronograph videos showing the CME expansion as viewed from each side of the sun. The STEREO Ahead satellite precedes the Earth as it circles the Sun. The STEREO Behind satellite follows behind the Earth in it's orbit of the Sun. (NOTE: Both STEREO videos will be replaced by better quality version when they become available in 48 hours.)
This not-squarely Earth-directed CME is moving at 1400 km/s according to NASA models. The CME should deliver a glancing blow to Earth's magnetic field during the late hours of June 8th or June 9th. High-latitude sky watchers should be alert for auroras when the CME arrives.
