Continued PSP/WISPR Observations of a Phaethon-related Dust Trail

We present an update to the first white-light detections of a dust trail observed closely following orbit asteroid (3200) Phaethon, as seen by Wide-field Imager for Parker Solar Probe (WISPR) instrument on NASA (PSP) mission. Here we provide summary and analysis observations over nine separate mission encounters between October 2018 August 2021 that saw spacecraft approach within 0.0277 au Phaethon. find photometric estimated mass properties be inline with those in initial publication, visual (V) magnitude approximately 16.1$\pm$0.3 per pixel, corresponding surface brightness 26.1 mag arcsec$^{-2}$, range $10^{10}$ kg - $10^{12}$ depending assumed properties. However, key finding this survey is discovery does not perfectly follow clear separation noted them increases function true anomaly, though may differ from Phaethon's little 1-degree periapsis.
