Encounter 8 Summary

Encounter 8 (04-24-2021 - 05-04-2021, with limited additional data 04-14-2021 - 05-15-2021)

This animation shows all WISPR full-field observations from the eighth PSP Mission Encounter (04-24-2021 - 05-04-2021). We have superimposed a grid showing heliocentric longitude and latitude. The timespan of this composite movie covers primarily the nominal science window when the spacecraft was within 0.25 au.

Note that some saturation of the data occurred in the inner part of the field of view on both Inner and Outer cameras, seen as the oval shaped features near the left-hand edge of each field of view.

You can download this movie as a 20Mb mp4 file.
