Imaging the chromosphere and prominences of the sun during an annular solar eclipse

A total solar eclipse is a spectacular celestial phenomenon, allowing direct observation of the Sun’s chromosphere, prominences, and corona without the need for a solar filter during the totality. In contrast, an annular solar eclipse, also known as the “ring of fire”, presents a different viewing experience. Throughout the entire process of an annular eclipse, eye protection via a solar filter remains essential and it prevents us from observing the faint chromosphere and prominences. However, with good site selection and a well-designed observing plan, it is possible to capture the chromosphere and prominences during an annular solar eclipse. In this article, I share a successful observation of the chromosphere and prominences acquired during the annular solar eclipse that occurred on October 14, 2023.
