In Parker Solar Probe's (PSP) first orbit, in situ thermal plasma measurements were made between 55 and 35 R_Sun from the Sun, an environment that has not been previously explored. During the first orbit of PSP, the spacecraft flew through two coronal mass ejections (CMEs) one on October 31, 2018 as it entered an encounter and the second CME on November 11, 2018 as it exited encounter. This CME on November 11 was directed away from the Earth and was not visible by L1 or Earth based telescopes due to this configuration. However, Parker Solar Probe and the STEREO A spacecraft were able to make observations of this CME. This paper looks at the basic characteristics of the closest in situ measured Coronal Mass Ejection to the Sun. We examine the solar source of this slow blowout CME as well as the evolution and thermal and kinetic energy associated with this CME.
