The Southwest Research Institute WFI team have delivered their first flight instrument (WFI-1) to the Integration and Test team for integration onto a flight PUNCH Observatory! WFI is a wide-field heliospheric imager, similar to an externally occulted coronagraph with a linear geometry. It will view a 40° wide field-of-view extending from 4.5° to approximately 45° from the Sun. WFI-1 will be integrated to a PUNCH spacecraft later this winter, in preparation for observatory environmental testing through the spring of 2024. PUNCH is scheduled to launch by early April of 2025.
We invite the community to the fifth PUNCH (Polarimeter to UNify the Corona and Heliosphere) Science Meeting (June 20-21, 2024) in Boulder, Colorado. Major science topics include the origin and evolution of the ambient solar wind and turbulence within it and the physics, tracking, and predictability of transient events including CMEs, CIRs, and shocks. Further details including abstract/registration deadlines will be announced soon on this web page and solar/heliospheric newsletters.
The topic of this telecon was in-situ/remote-sensing/modeling synergies. Click to go to meeting page with links to presentations.
The Naval Research Laboratory team has completed integration and test of the PUNCH Narrow Field Imager (NFI), and delivered the instrument to SwRI for integration into the PUNCH Observatories! NFI is an externally occulted coronagraph based on NRL’s CCOR design. it covers the central part of the PUNCH field of view, from approximately 5 to 32 solar radii from the Sun itself. NFI will be the first primary instrument integrated to a PUNCH Observatory, in late calendar year 2023, and will fly with the rest of PUNCH when the mission launches (est. April 2025).
The Colorado Space Grant Consortium successfully delivered its student collaboration instrument, the STudent Energetic Activity Monitor (STEAM), for integration into the PUNCH OBservatories! STEAM is a soft X-ray spectrometer build around a solid state detector, with a small microprocessor to interface with the spacecraft. STEAM will view the Sun as a star, and probe the energetics of solar falres and coronal heating throughout the PUNCH mission. STEAM will be integrated onto the Narrow Field imager (NFI) Observatory and fly with NFI when the mission launches (est. April 2025).
The fourth PUNCH (Polarimeter to UNify the Corona and Heliosphere) Science Meeting was successfully held in the summer of 2023 in Boulder, CO. We solicited abstracts for poster/oral presentations from the community on subjects related to this topic. Click to go to meeting page with links to presentations and posters.
