Dominant direction of the dimming expansion at the end of the impulsive phase for May 8, 2024. Top: Dimming area in the different sectors (shown in the bottom panels in blue), revealing its maximum extent in sector 10. Bottom: Cumulative dimming pixel mask outlined in gray with red contours. The blue lines indicate the 12 sectors. The dashed purple line gives the sector of the dominant dimming development. The small black dots show the dimming edges at the farthest edges from the source (one of them is in the sector of the dominant dimming direction and the other is in sector 3), which were used to generate the 3D CME cones at different heights, associated widths, and inclination angles.
