Maps of the total brightness tB intensity as a function of time and heliocentric distance for sectors A (left panels), B (middle panels), and C (right panels) for some of the most representative radial directions considered in the analysis. Each time series of the total brightness tB is normalized to zero mean and unit standard deviation. The sector label is reported at the top of each corresponding panel, as well as the radial direction, expressed in terms of the polar angle (PA) value, measured counterclockwise from the north pole. The white and red arrows indicate outflowing and inflowing structures, respectively. The color gradient from blue to yellow progresses from low to high values of the total brightness. Yellow represents brighter structures.
