When was this system first observed? Maybe that's stated somewhere in the article, but I don't see it. – Athaenara ✉ 23:01, 23 October 2021 (UTC) reply

It is a relatively bright star. It was catalogued over a century ago, then named as a variable star in the first half of the twentieth century. Other discoveries followed as detailed in the article references. Lithopsian ( talk) 11:40, 24 October 2021 (UTC) reply
