From Wikipedia, the free encyclopedia

A keogram is a plot of time versus latitude, created from individual images captured over the course of a period of time. [1]. They are commonly used to display auroral activity as recorded by all-sky cameras over the course of a night. [2] They may be used to display weather information over the course of years in order to highlight long-term trends. The word "keogram" derives from the Inuit word for aurora borealis. [3]
