Encounter 24 (2025-06-09 - 2025-06-30, with limited additional data 2025-06-06 - 2025-07-02)
This animation shows all L3 WISPR full-field observations from the twenty-second PSP Mission Encounter (2025-03-18 - 2025-03-27). We have superimposed a grid showing helioprojective longitude and latitude, and a scale representation of the size and location of the Sun in the observations using the SDO/HMI Carrington map for this time period. The velocity and distance metrics displayed on the movies correspond respectively to the spacecraft's heliocentric velocity in kilometers per second, and its distance from the Sun's center in units of solar radii (where 1 solar radius = 695,700km). The "FOV Range" label provides the plane-of-sky distance limits of the inner and outermost edges of the fields of view, in units of solar radii. The horizontal blue line indicates the orbital plane of PSP. The timespan of this composite movie covers only the nominal science window when the spacecraft was within 0.25 au; a limited amount of data outside of this range may be available at the below links.
You can download this movie directly as an 105MB mp4 file. This sequence is also available as data processed via the LW Algorithm developed by Dr. Guillermo Stenborg (JHUAPL) and detailed in Appendix A of Howard et al. 2022 (ApJ, 936, id.43. DOI 10.3847/1538-4357/ac7ff5). Please contact the team for access to this data, which will be posted here one year after the acquisition of those observations. Team contact information can be found in Section 1.2 of the WISPR User's Guide [PDF link].

Solar Features
TBD
Comets and planets
A few Kreutz sungrazers are visible, along with two small "non-group" comets. Their exact identities still to be determined.
Planets as follows:
Operations summary
On June 20, from the start of the day through 22:00 UT, WISPR-I images were taken in full detector resolution (1920x2048) instead of the normal 2x2 binning employed for most science observations (the 960x1024 images). The different resolutions introduce complications for the processing of higher level data products as a consistent set throughout the orbit, so binned L2 versions of these full-resolution files were created such that there would be a single, synoptic data set. These binned files have been placed inside in the L2/20250620 directory alongside the rest of the data for that dat. The original, full resolution L2 files can be found in L2/20250620/fullres. If you download the L2 zip file linked below, the full-resolution files are included in there. All L2b, L3 and LW fits files, as well as movies and pngs, are based only on the binned L2s -- there are no L2b or L3 files for the full-resolution data.
Miscellaneous notes
None.
