A Three-Point CME Reconstruction Including PSP/WISPR Imagery

On 2018 November 5, about 24 hours before the first close perihelion passage of Parker Solar Probe (PSP), a CME entered the field of view of the inner detector of the WISPR instrument onboard PSP, with the northward component of its trajectory carrying the leading edge of the CME off the top edge of the detector about four hours after its first appearance. We connect this event to a very small jet-like CME observed from 1 AU by coronagraphs on both the SOHO and STEREO-A spacecraft. This allows us to make the first three-dimensional reconstruction of a CME structure considering observations from very close to the Sun, as well as two 1 AU observatories at different locations. The CME may be small and jet-like as viewed from 1 AU, but the close-in vantage point of PSP/WISPR clearly demonstrates that the CME is not intrinsically jet-like, but instead has a structure consistent with a flux rope morphology.
