Two egg-shaped plasmoids are found at 306 000 and 266 000 km, respectively The farthest limit of the reconstruction (top) is located 701 000 km from Earth. The number of Birkeland currents is 56 at the top, converging to 28 at the plasmoids and eventually converging and twisting into four large filaments. If the current oscillates or is sporadic [36, p. 34], the four can separate back to 56 filaments. Whether 56 or 4, or some number in-between, the filaments flow over and past the rotating Earth.
