Fore-Warnings
This dynamic active region, which has already popped off 12 flares (C and M class) in just two days (Oct. 8-10, 2012), is rotating into view. The region may be a harbinger of geo-effective activity to come. This wavelength of extreme ultraviolet light (131 Angstrom) can observe plasma at temperatures up to 10 million degrees. Another active region above this one is also quite large and could also produce some major solar storms.
