  • Encounter 8 Summary

    Encounter 8 (04-24-2021 - 05-04-2021, with limited additional data 04-14-2021 - 05-15-2021)

    This animation shows all WISPR full-field observations from the eighth PSP Mission Encounter (04-24-2021 - 05-04-2021). We have superimposed a grid showing heliocentric longitude and latitude. The timespan of this composite movie covers primarily the nominal science window when the spacecraft was within 0.25 au.

    Note that some saturation of the data occurred in the inner part of the field of view on both Inner and Outer cameras, seen as the oval shaped features near the left-hand edge of each… more

  • Encounter 8 Data Release, and website update

    Data for Encounter 8 is available (04-24-2021 - 05-04-2021, with limited additional data 04-14-2021 - 05-15-2021). All data can be obtained from the various links provided on our WISPR Data page.

    Also, the team apologizes for the recent downtime of the WISPR website. At time of writing, the WISPR database query tool remains unavailable, but all data are easily obtained via the WISPR Data page. Also we will remind users that copies of our data archives can always be obtained via the Virtual Solar Observatory

  • WISPR data released

    On November 12, 2019, data recorded by our Wide-field Imager for Parker Solar Probe (WISPR) imaging instrument aboard the NASA Parker Solar Probe (PSP) mission became publicly releasable! That means you can now download all the WISPR data from PSP's first two 'encounters' over on our data retrieval page, where we provide links to the science data (FITS format), and browse images in PNG and MPG format (as seen below). Moving forward, the data from future encounters will be made available within 90 days of receipt of all telemetry for that encounter with the next data set (Encounter 3) anticipated to be released in early 2020.

    To celebrate the release of the WISPR data, below are two movies from each of the first two PSP encounters. The movies show the combined fields of view of the inner and outer WISPR telescopes. 

    In these movies, the Sun is outside of the left-hand edge of the field of view (at 0-degrees longitude on the x-axis scale shown… more

The Wide-field Imager for Parker Solar PRobe (WISPR) is the sole imager aboard the Parker Solar Probe (PSP) mission, which launched in August 2018. PSP is a unique mission designed to orbit as close as 7 million km (9.86 solar radii) from Sun center. WISPR employs a 95◦ radial by 58◦ transverse field of view to image the fine-scale structure of the solar corona, derive the 3D structure of the large-scale corona, and determine whether a dust-free zone exists near the Sun. WISPR is the smallest heliospheric imager to date yet it comprises two nested wide-field telescopes with large-format (2 K × 2 K) APS CMOS detectors to optimize the performance for their respective fields of view and to minimize the risk of dust damage, which may be considerable close to the Sun. The WISPR electronics are very flexible allowing the collection of individual images at cadences up to 1 second at perihelion or the summing of multiple images to increase the signal-to-noise when the spacecraft is further from the Sun. The dependency of the Thomson scattering emission of the corona on the imaging geometry dictates that WISPR will be very sensitive to the emission from plasma close to the spacecraft in contrast to the situation for imaging from Earth orbit. WISPR will be the first ‘local’ imager providing a crucial link between the large-scale corona and the in-situ measurements.
