Visible light observations of a Coronal Mass Ejection (CME) acquired by the Wide Field Imager for Solar Probe (WISPR) telescopes onboard the Parker Solar Probe (PSP) mission on November 19-20, 2021. The PSP and CME are located just 10 million km from the solar surface and PSP is approaching the CME from below. The Kelvin-Helmholtz instabilities (KHI) appear as vortices at the interface between the CME and the ambient solar wind. The arrows in the embedded snapshots mark the KHI. The final snapshot shows a thin line of solar plasma that remains after the deformation of the KH vortices. This is a first-of-its-kind observation of this unique phenomenon in the solar corona.
