Campaign: Parker Solar Probe 24^th Perihelion

June 17 - 22, 2025

Parker Solar Probe’s Perihelion 24 occurred on June 19 2025, at 09:31 UT. The inbound phase of this encounter was behind the limb, with perihelion occurring over the East limb. Parker's footpoints then rapidly advanced on disk, reaching the central meridian on 6/21 and remained on disk approaching the West limb slowly through the outbound phase of the encounter. Footpoint predictions were provided daily from Tuesday June 17th through Sunday June 22nd covering from before East limb package through to Parker passing the central meridian.
