Top row: composite images on three dates (Table 1) shown with a common display range from −0.01 to 0.02 adu pixel⁻¹. Bottom row: same images from the top row contoured from 0.0004 adu pixel⁻¹ in steps of 0.002 adu pixel⁻¹. Contours are smoothed over 8 × 8 pixel boxes. Yellow arrows show the projected antisolar direction while white arrows show the projected negative heliocentric velocity vector, from Table 1. The two directions are overlapping in the 2023 data. A 1″ scale is common to all panels.
