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.[5]

Discovery and observations

[edit]

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.[4] It was a 6th-magnitude object located within the constellation Leo Minor at the time of its discovery,[a] and had started its outbound flight upon reaching perihelion about two days earlier.[3]
