Polar plot showing the locations (HCI longitudes and distances from the Sun in solar radii) at several times for PSP (o) andthe predicted locations of the CME (*) using the trajectory found from the feature tracked in the WISPR-I images. The locations of each are plotted at the same six times: every 6 h from 26 January at 0 UT to 27 January at 6 UT, the approximate time interval that the CME was observed by WISPR. PSP, heading toward perihelion, is approaching the path of the CME. The blue arrow shows the direction to STEREO-A and the green arrow the direction to Earth at the start of the time interval, 26 January at 0 UT.
