Thermal infrared measurements of near-Earth objects provide critical data forconstraining their physical properties such as size. The NEOWISE mission hasbeen conducting an all-sky infrared survey to gather such data and improve ourunderstanding of this population. While automated routines are employed toidentify the majority of moving objects detected by NEOWISE, a subset ofobjects will have dynamical properties that fall outside the window detectableto these routines. Using the population of known near-Earth objects, we haveconducted a manual search for detections of these objects that were previouslyunreported. We report 303 new epochs of observations for 299 unique near-Earthobjects of which 239 have no previous physical property characterization fromthe NEOWISE Reactivation mission. As these objects are drawn from a list withinherent optical selection biases, the distribution of measured albedos isskewed to higher values than is seen for the diameter-selected populationdetected by the automated routines. These results demonstrate the importanceand benefit of periodic searches of the archival NEOWISE data.
