GONG supports Parker Solar Probe's 25th encounter

Parker Solar Probe is approaching its 25th encounter, with perihelion expected on September 15 at 20:22 UT. The magnetic connectivity prediction issued on 12 Sep 2025 includes modeling predictions based on GONG magnetic field observations. For image on the right - Helioprojective PSP predicted footpoints: one footpoint per day plotted on the solar disk. Colored dots show predictions from a range of models. Gold squares show the consensus value for each day. Black contours show the full width half maximum for the Kent distribution (en.wikipedia.org/wiki/Kent_distribution) fitted to each set of footpoints (Courtesy of Sam Badman). This is the first of seven updates (for future updates see here).
