Comet Kaho–Kosik–Lis, also known as C/1936 O1, is a long-period comet that became barely visible to the naked eye in July 1936. It is the parent body of the Psi Scorpiids meteor shower.

Discovery and observations

The comet was simultaneously discovered by three astronomers, Shigeru Kaho (Japan), Stefan M. Kozik (Turkmen SSR) and Władysław Lis (Poland) on the night of 17 July 1936. It was a 6th-magnitude object located within the constellation Leo Minor at the time of its discovery, and had started its outbound flight upon reaching perihelion about two days earlier.
