  Thermal infrared measurements of near-Earth objects provide critical data for
constraining their physical properties such as size. The NEOWISE mission has
been conducting an all-sky infrared survey to gather such data and improve our
understanding of this population. While automated routines are employed to
identify the majority of moving objects detected by NEOWISE, a subset of
objects will have dynamical properties that fall outside the window detectable
to these routines. Using the population of known near-Earth objects, we have
conducted a manual search for detections of these objects that were previously
unreported. We report 303 new epochs of observations for 299 unique near-Earth
objects of which 239 have no previous physical property characterization from
the NEOWISE Reactivation mission. As these objects are drawn from a list with
inherent optical selection biases, the distribution of measured albedos is
skewed to higher values than is seen for the diameter-selected population
detected by the automated routines. These results demonstrate the importance
and benefit of periodic searches of the archival NEOWISE data.
