Talk:BY Draconis variable

Procyon
I was surprised to see Procyon listed as a possible BY Dra variable. A reference to a popular book is not really a primary source, does anyone have a reference to an actual journal publication? If not, I propose to delete the mention. Timb66 (talk) 01:38, 30 August 2019 (UTC) — Preceding unsigned comment added by Timb66 (talk • contribs) 01:36, 30 August 2019 (UTC)
