Structure of the Plasma near the Heliospheric Current Sheet as Seen by WISPR/Parker Solar Probe from inside the Streamer Belt

Parker Solar Probe (PSP) crossed the heliospheric current sheet (HCS) near the perihelion on encounters E8 and E11, enabling the Wide- field Imager for Solar Probe (WISPR) to image the streamer belt plasma in high resolution while flying through it. With perihelia of 16 R $_\ensuremath\odot$ and 13 R $_\ensuremath\odot$ for E8 and E11, respectively, WISPR images enable investigation of the structure of density encasing the HCS at much higher resolution than reported previously. As PSP flies closer to the Sun, fine-scale stru ...

Extracting the Heliographic Coordinates of Coronal Rays Using Images from WISPR/Parker Solar Probe

The Wide-field Imager for Solar Probe (WISPR) onboard Parker Solar Probe (PSP), observing in white light, has a fixed angular field of view, extending from 13.5$^\ensuremath\circ$ to 108$^\ensuremath\circ$ from the Sun and approximately 50$^\ensuremath\circ$ in the transverse direction. In January 2021, on its seventh orbit, PSP crossed the heliospheric current sheet (HCS) near perihelion at a distance of 20 solar radii. At this time, WISPR observed a broad band of highly variable solar wind and multiple coronal rays. For si ...

Tracking solar wind flows from rapidly varying viewpoints by the Wide-field Imager for Parker Solar Probe

\ Aims: Our goal is to develop methodologies to seamlessly track transient solar wind flows viewed by coronagraphs or heliospheric imagers from rapidly varying viewpoints. \ Methods: We constructed maps of intensity versus time and elongation (J-maps) from Parker Solar Probe (PSP) Wide- field Imager (WISPR) observations during the fourth encounter of PSP. From the J-map, we built an intensity on impact-radius-on- Thomson-surface map (R-map). Finally, we constructed a latitudinal intensity versus time map (Lat-map). Our metho ...

Evolution of a steamer-blowout CME as observed by imagers on Parker Solar Probe and the Solar Terrestrial Relations Observatory

Context. On 26-27 January 2020, the Wide-field Imager for Solar Probe on Parker Solar Probe (PSP) observed a coronal mass ejection (CME) from a distance of approximately 30 R$_\ensuremath\odot$ as it passed through the instrument s 95\textdegree field-of- view, providing an unprecedented view of the flux rope morphology of the CME s internal structure. The same CME was seen by Solar Terrestrial Relations Observatory-Ahead (STEREO-A), beginning on 25 January. \ Aims: Our goal is to understand the origin and determine the traj ...

Trajectory Determination for Coronal Ejecta Observed by WISPR/Parker Solar Probe

TheWide-field Imager for Solar Probe(WISPR) onboard theParker Solar Probe(PSP), observing in white light, has a fixed angular field of view, extending from 13.5(circle)to 108(circle)from the Sun and approximately 50(circle)in the transverse direction. Because of the highly elliptical orbit of PSP, the physical extent of the imaged coronal region varies directly as the distance from the Sun, requiring new techniques for analysis of the motions of observed density features. Here, we present a technique for determining the 3D t ...

Near-Sun observations of an F-corona decrease and K-corona fine structure

Remote observations of the solar photospheric light scattered by electrons (the K-corona) and dust (the F-corona or zodiacal light) have been made from the ground during eclipses and from space at distances as small as 0.3 astronomical units to the Sun. Previous observations of dust scattering have not confirmed the existence of the theoretically predicted dust-free zone near the Sun. The transient nature of the corona has been well characterized for large events, but questions still remain (for example, about the initiat ...

Simulating White Light Images of Coronal Structures for WISPR/Parker Solar Probe: Effects of the Near-Sun Elliptical Orbit

The three-to-five-month elliptical orbit of Parker Solar Probe (PSP), approaching within 10 solar radii of the Sun, will allow the Wide-field Imager for Solar Probe (WISPR) to view the corona with unprecedented spatial resolution from multiple viewpoints. WISPR has a wide fixed angular field of view, extending from 13.5 degrees to 108 degrees from the Sun and approximately 50 degrees in the transverse direction, but the physical extent of the imaged coronal region varies directly with the distance of the spacecraft from the ...
