Fig. 15From: Two current systems in the preliminary phase of sudden commencements in the magnetosphereDistributions of \({V}_{A}\) in the 14.4 MLT meridian plane and the equatorial plane. The type L current system that flows in the 14.4 MLT plane is also shown. The white dotted arrow indicates the L value of the field line where FPC is converted to FAC (L≈7). The color of the current lines denotes \({V}_{A}\)Back to article page
