This animation shows all WISPR full-field observations
from the fifteenth PSP Mission Encounter (2023-03-12 - 2023-03-23),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 ).
The WISPR Team 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.

The CGAUSS project is funded by the German Aerospace Center (DLR) under grant 50OL2301 as the national contribution to the Parker Solar Probe mission.
The WISPR project is led by the Naval Research Laboratory (NRL), Washington DC, USA with Dr. Mark Linton as Principal Investigator (PI). The former PI was Dr. Russell A. Howard with Deputy PI and Project Scientist Dr. Angelos Vourlidas, now both at Johns Hopkins University, Applied Physics Laboratory, Laurel, MD, USA.
