Trajectory of PSP in a rotating frame of reference with the Sun, which when data are available, is coloured by the AM flux in the protons (core plus beam, top left), alpha particles (top right), magnetic stresses (bottom left), and their total (bottom right). Both the AM flux in the alpha particles and that stored in the magnetic stresses were multiplied by three, so that they are visible in comparison to the scale of the proton AM flux. In the background, the average magnetic field polarity observed by FIELDS over one hour intervals colours parker spiral field lines, which are ballistically-mapped using the radial wind speed observed by SPC (as the data available from SPC cover a much longer time period than SPAN). A fast wind stream (F1) and a slow wind stream (S1) are highlighted in orange and cyan, respectively. The bottom rightpanel is zoomed-out slightly to show the extent of the observations in comparison to the system size.
