The chromosphere, as seen in many eclipse images and video, appears intensely white in its lowermost layers and then has a characteristic purplish pink hue for most of
Why is the chromosphere purple? Read more »
Descriptions of total solar eclipses observed from the very edge of the path of totality are few and far between. So we would like to share our experience
