Le immagini di un'enorme tempesta solare sono state catturate dal Solar Dynamics Observatory della NASA lo scorso sabato 8 marzo. L'esplosione dalla superficie del Sole ha prodotto quello che è noto come uno "tsunami solare", con una raffica di particelle solari che viene “sputata” nello spazio profondo.
L'esplosione e il suo bagliore ultravioletto sono durati poco più di un'ora. Di conseguenza, la Terra potrebbe essere colpita da tempeste solari tra l'11 marzo e il 13 marzo.
Secondo gli analisti del NOAA, ci si aspettava che un’esplosione di massa solare (CME, coronal mass ejection) passasse appena dietro la Terra mentre l'altra doveva passarle davanti. Il video pubblicato dal Solar Dynamics Observatory della NASA mostra un'esplosione di verde e blu proveniente dalla macchia solare, chiamata AR2734.
