Encounter 23 (2025-03-18 - 2025-03-27, with limited additional data to 2025-03-29)
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].
