In case there's any interest, this Archiv page includes a PDF. https://arxiv.org/abs/1911.05068 https://arxiv.org/abs/1911.05068 "We visually examine the images for a subset of about 24,000 candidates, superseding the 2016 study with a sample ten times larger. We find about ∼100 point sources visible in only one epoch in the red band of the USNO which may be of interest in searches for strong M dwarf flares, high-redshift supernovae or other catagories of unidentified red transients. Comments: SETI meets time domain astronomy."
