[atlas] life-cycle of a probe?

Hi folks, is there a way to find out when a particular probe (under my control[1]) was seen by a/the collector(s) for the first time? The best I have come up with is to look at the raw data download, but I'm not sure that the data has been preserved for raw download in the "early days". Thanks, Wilfried [1] just in case, I am interested in ID 466 and 414
