The Corona is the Sun's outer atmosphere. It is visible during total eclipses of the Sun as a pearly white crown surrounding the Sun. The corona displays a variety of features. However, during the few fleeting minutes of totality few, if any, changes are seen in these coronal features. The Emission Line Corona. The LASCO...
