A very small, dim and modest night cloud play was shown at night on July 22/23, 2021. In the form of mainly gauze and belts.

The almost full Moon hung in the shallow southern sky with Jupiter and Saturn.

The observation site is Kallela's slave station in Kalanti, Uusikaupunki, the residents of the stable kept company for the night owls :)
