NASA. LARGE FORMAT. Beautiful and rare observation of an exceptional solar flare. A long filament of solar material hovering in the sun's atmosphere, the corona, erupted into space. The coronal mass ejection moved at more than 900 miles per second. The coronal mass did not head directly toward Earth but made contact with Earth's magnetic environment, or magnetosphere, causing auroras to appear on Earth a few days later. August 2012.period chromogenic print. Numbering in the margin on the front. Legend on label on back. 40.6 X 40.6CM with margins.
