Figure 1. Photospheric regions of the open lines of the magnetic field of the Sun +1, +2, - 1, -2 (black small circles), corresponding subsectors of the field on the source surface (polygons), solar activity phenomena: coronal holes with the boundaries shown by smooth curves, active filaments (line segments), active regions (black-and-white figures), and flares (crosses) in the (a) CR 1920 and (b) CR 1921 rotations. The dashed line shows the trajectory of the Earth's helioprojection.
