Twin M-class Solar Flares
Although visually it only looks like a single flare, sensitive scientific instruments indicated that these were actually two flares very close together (June 13, 2012) from Active Region 1504. At 12:47 UT a M1.5 solar flare started and only five minutes later a M1.9 flare erupted from the same active region. The M1.5 flare peaked at 14:08 and ended at 15:00 UT. The M1.9 flare peaked at 14:35 and ended at 15:56 UT. The image and video clips were taken in extreme ultraviolet light. Indicators show that the coronal mass ejection associated with these flares might impact Earth a few days later.
