Each record sits in this year because its source places it here, or because a conversion of the source’s date, stated on the record, does. That is a placement, not a settled date, and not a complete account of the year. “No region assigned” means the collection has not fixed where the act took place. How to read a record
The NASA/JPL catalogue attributes the discovery observation of 4914 Pardina to C. U. Cesco at the Felix Aguilar Observatory, El Leoncito, on 9 April 1969.
Limits: Catalogue attribution, not firsthand testimony or a claim of the first human sighting. The corresponding DISCOVERY.DB fields supply Cesco as discoverer and confirm El Leoncito; the naming citation concerns a different person.
