In situ Solar Orbiter/MAG observations during the rise in the magnetic field magnitude detected from June 7, 2020, 02:13 UT to June 8, 2020, 13:47 UT (first panel of Fig. 1a). From left to right: temporal variation and magnetic hodograms (displayed both as a function of time and projected onto the associated planes) of the RTN field components. The time profile of the curvature ρ of the magnetic field vector rotation in the T − N plane perpendicular to the sampling direction (estimated from the large-scale EMD-reconstructed trends of the B_T and B_N components, which are represented by the thick continuous lines) is displayed in the bottom rightmost panel. The full dot and star in the B_T − B_N magnetic hodogram refer to the starting and ending time point. Blue and red colors mark the upstream and downstream helical structure, respectively. The start and end, duration Δt, and angle φ between the helical structure axis and the sampling direction, are also reported for each event.
