Flaring together: A preferred angular separation between sympathetic flares on the Sun
Sympathetic solar flares are eruptions that occur nearby in space and time, driven by an apparent interaction between the active regions in which they are triggered. Their statistical existence on the Sun has yet to be firmly established. The work provides strong statistical evidence for the existence of sympathetic flares on the Sun, and we propose an interpretation of the observed angular scale of the phenomenon, based on the separation between magnetic field line footpoints derived from potential field source surface extrapolations.
