ACE and Wind observations during the period from March 14, 2012, to March 20, 2012. From top to bottom: SW proton speed, proton density, proton temperature, magnetic field magnitude, magnetic field RTN components, magnetic field azimuthal angle in the RTN coordinate system complemented with the two possible nominal Parker spiral angles (red, negative; green, positive) calculated from the proton speed and accompanied by its polarity (red, negative; green, positive; yellow, ambiguous), magnetic field latitudinal angle in the RTN coordinate system, total pressure, and plasma β.
