NASA Captures Solar Flux Rope, CME Precursor Seen For The First Time On Its Own

“Voirlidas credits this first sighting to three things. First, the team looked far enough back in time, when previous searches have often only looked a few minutes back. Second, the sun obliged its viewers with the perfect angle at which to see the tell-tale loops of the flux rope. SDO’s cameras could look right down the center of the rope, like looking down the tunneled center of a slinky. Third, AIA’s cameras capture imagery that no other cameras do: light at the 131 Angstrom wavelength, which shows solar material heated to temperatures of 10,000,000 K (18,000,000 F / 10,000,000 C). In images of the same region at the same time showing cooler material, the flux rope doesn’t show up at all. AIA scientists chose to include a filter to view this unprecedentedly high temperature because they posited that flares could heat the corona to those temperatures. Apparently the same...
