Polar view maps. Polar view maps of the local Hurst exponent values in the Northern Hemisphere for the time interval 14–22 March 2015. The coordinates are AACGM latitude, from \(50^{\circ }\)N to the north pole, and the magnetic local time (MLT), with the local noon at the top and local midnight at the bottom. Concentric circles are magnetic parallels drown at \(10^{\circ }\). On each map, the temporal trend of AE index for the corresponding day is reported using the same scale in all the graphs
