Solar wind conditions upon the occurrence of magnetic reconnection. The corner plot shows the joint 2D distributions of the solar wind speed V, plasma parameter log β, temperature T, and density n for the whole period of measurements. The superimposed blue dots indicate the value of these parameters around the intervals where magnetic reconnection was observed. The top panels of the corner plot then show the 1D histograms of these quantities for the whole month (in black) and for reconnection inflow conditions (in blue).
