Kinematics in MOSAIK3D volume results. (a) Box plots of speeds per WISPR frame. (b) Speeds of the structure’s centroid (solid red) and closest/farthest points from the Sun (dashed black) as triangles and diamonds, respectively. (c) Number of points included in the MOSAIK3D analysis for each WISPR frame. The deterioration of speed statistics ∼7 hr into the observations is due to the declining number of points leading to nonrepresentative results.
