Encounter 7 (01-11-2021 - 01-31-2021, with limited additional data 12-11-2020 - 02-19-2021
This animation shows all WISPR full-field observations from the seventh PSP Mission Encounter (01-11-2021 - 01-31-2021). 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 16Mb mp4 file.

Comets and planets
The following comets were observed during this encounter. Note that some of the data sets occur outside the nominal Encounter window and, in many cases, the spacecraft may have a non-standard roll orientation. Thus only limited observations would have been made for the comet in question. If you have trouble locating the comets in any of these data or questions regarding the proper treatment of the comet observation data, please contact the WISPR comet observation coordinator, Karl Battams - karl.battams[at]nrl.navy.mil.
