  We present the identification and preliminary analysis of a dust trail
following the orbit of (3200) Phaethon as seen in white light images recorded
by the Wide-field Imager for Parker Solar Probe (WISPR) instrument on the NASA
Parker Solar Probe (PSP) mission. During PSP's first solar encounter in
November 2018, a dust trail following Phaethon's orbit was visible for several
days and crossing two fields of view. Preliminary analyses indicate this trail
to have a visual magnitude of 15.8 $\pm$0.3 per pixel and a surface brightness
of 25.0 mag arcsec$^{-2}$ as seen by PSP/WISPR from a distance of $\sim$0.2 au
from the trail. We estimate the total mass of the stream to be
$\sim(0.4-1.3){\times}10^{12}$ kg, which is consistent with, though slightly
underestimates, the assumed mass of the Geminid stream but is far larger than
the current dust production of Phaethon could support. Our results imply that
we are observing a natural clustering of at least some portion of the Geminid
meteor stream through its perihelion, as opposed to dust produced more recently
from perihelion activity of Phaethon.
