<div>Uma forte tempestade de radiação protónica esta progresso. As particulas de alta energia foram ejectadas pelos eventos de segunda feira e de ontem. Prevêm-se fortes auroras até media latitude. A absorção de radio nos polos está "ao rubro" sendo praticamente impossivel comunicar em HF pelas zonas polares ou de e para lá! Nunca tinha visto o "mataborrão" como está hoje. Neste momento o fluxo integral 10MeV é maior que 1000pfu e continua a subir. Entretanto o Kp index está baixo, indicando uma calmia geomagnética (Kp=1) . Devido a possivel chegada da CME produzida pela FLARE X 5.4, prevista para amanhã, é possivel que o geomagnetismo fique quase no topo da escala, visto que a CME foi considerável. Possibilidades de se repetirem os eventos actuais continuam.</div>
