Stellar image just in one DSS, not present in other

At this coords, in IRSA finder chart, only in plat DSS poss1_red: 1956-03-14 there is a quite bright stellar image not present in other wavelenghts and other surveys, (maybe something in AKARI N60), see IRSA: Finder Chart

The Legacy Surveys data are much deeper than DSS, so my guess would be that it’s a chance tranient in that one DSS plate – it looks sligthly trailed, so maybe an asteroid.
