Encounter 10 (2021-11-16 - 2021-11-26, with limited additional data 2021-11-11 - 2022-01-06)
This animation shows all WISPR full-field observations from the tenth PSP Mission Encounter (11-16-2021 - 11-26-2021), 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). We have superimposed a grid showing heliocentric longitude and latitude, and a scale representation of the size and location of the Sun in the observations. 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 timespan of this composite movie covers only the nominal science window when the spacecraft was within 0.25 au.
You can also download this movie directly as a 303MB mp4 file. It is also available in the same format using the L3 images, which can be downloaded here as a 58MB mp4 file.

Miscellaneous Notes:
- A further update to straylight model for the outer telescope was applied to account for the new, closer perihelion distance.
- The outer telescope had an incorrect bias subtracted between November 18 16:24 and November 25 00:30 due to the images being commanded at a different gain setting than the bias images. The bias subtracted off in sufficient, which left a remnant bias in the images and masked pixels. Using the masked pixels this was removed. Due to being commended at a different gain level, an altered calibration factor was required to normalize the intensities with respect to the rest of the encounter. These issues have all been fixed in the L2 and L3 products.

- Mars: From 2021-11-19 ~10UT
- Mercury: 2021-11-19 ~18UT
- Saturn: 2021-11-21 ~09UT
- Jupiter: 2021-11-21 ~15UT
- Venus: 2021-11-22 ~07UT
- Earth: 2021-11-24 ~07UT
