Wow, what a mother lode in the March issue (vol. 167, #3) of AJ. Transition objects galore: Explicit comets (including high, supervolatile-based activity), Kuiper Belt- and Jupiter Trojan-objects (likely quasi-comets that just don’t warm up enough), and general sky search:

“Digital tracking” allows fainter detection via image stacking; it’s the astronomical equivalent of hitting a trifecta/doubling down, etc. In this case, it works better for distant objects like Transneptunians, due to their slow and predictable tracks. Close objects like NEOs, not so much… but with sufficient computer power, NEOs work too. And this is before Vera Rubin Obs.
