Campaign: Parker Solar Probe 15^th Perihelion

March 13 - 21, 2023

The fifteenth encounter of Parker Solar Probe provided observations as close as 13.3Rs (0.062 au) to the Sun, with perihelion occurring on 2023 March 17^th. This encounter had tremendous opportunities for conjunction studies with both remote sensing Earth-based observatories and in situ observatories throughout the inner heliosphere. This included both radial and Parker spiral alignments with Mars near 1.5 au, STEREO-A and Earth near 1 au, and Solar Orbiter and BepiColombo near 0.5 au. To support coordinated observing, WHPI and the Parker Solar Probe modeling team partnered to supply footpoint predictions for Encounter 15. The first prediction was issued on 2023 March 13^th, followed by daily updates from 2023 March 16^th though 2023 March 21^st. Footpoint predictions also included updates on the likelihood of flare activity from currently visible active regions based on the CCMC Flare Scoreboard.
