vilkkautena
Vilkautena is a Finnish word that describes a fleeting glimpse or a brief flash of light. It can refer to a sudden, momentary appearance of something, often unexpected. The term is commonly used in everyday language to describe visual phenomena that are transient and quick. For example, one might see a vilkautena of lightning in the distance or catch a vilkautena of a rare bird as it flies by.
The concept of vilkautena implies something that is not sustained but rather appears and disappears rapidly.
