Interactions of Active Regions

February 20, 2014
Observations in two wavelengths of extreme UV light revealed the magnetic connections between a pair of large and dynamic active regions observed over almost a two-day period (Feb. 2-4, 2014). The tangles of lines between the two regions are actually high-energy particles spinning along the magnetic field lines that arch between them. The numerous bright flashes are solar flares erupting. Active regions are areas of intense magnetism and appear as sunspots in white light images. The color table of the AIA 193 images was changed to help bring out the magnetic field lines.
