2010 August 1 SDO/AIA 304-Angstrom view of X-ray flare and filament eruption
At approximately 0855 UTC on August 1, 2010, a C3.2 magnitude soft X-ray flare erupted from NOAA Active Sunspot Region 11092 (1092). Latest updates on website: prop.hfradio.org At nearly the same time, a massive filament eruption occurred. Prior to the filament's eruption, NASA's Solar Dynamics Observatory (SDO) AIA instruments revealed an enormous plasma filament stretching across the sun's northern hemisphere. When the solar shock wave triggered by the C3.2-class X-ray explosion plowed through this filament, it caused the filament to erupt, sending out a huge plasma cloud. In this movie, taken by SDO AIA at the 304-Angstrom wavelength, a cooler shock wave can be seen emerging from the origin of the X-ray flare and sweeping across the sun's northern hemisphere into the filament field. The impact of this shock wave may well have propelled the filament into space. This movie seems to support this analysis: Despite the approximately 400000 kilometer distance between the flare and the filament eruption, they appear to erupt together. How can this be? Most likely they're connected by long-range magnetic fields (remember: we cannot see these magnetic field lines unless there is plasma riding these fields). NOTE: The energy that will likely be transferred by the plasma mass that was ejected by the two eruptions (first, the slower-moving coronal mass ejection originating in the C-class X-ray flare at sunspot region 1092, and, second, the faster-moving plasma ejection originating <b>...</b>
