Determining the state of the corona prior to coronal mass ejections (CMEs) is crucial to understanding and ultimately predicting solar eruptions. A common and compelling feature of CMEs is their three-part morphology as seen in white light observations of a bright expanding loop, followed by a relatively dark cavity, and lastly a bright core associated with an erupting prominence/filament.
Here is a catalogue providing detailed analysis of 98 white light cavities observed by MLSO's Mk4 coronameter:

Dr. Scott McIntosh is Observatory Director in the High Altitude Observatory at the National Center for Atmospheric Research. His primary focus of research is chromospheric dynamics and understanding the physical connectivity between the Sun's cool surface and its considerably hotter corona.
The slides in this collection were written By P. Charbonneau and O.R. White–April 18, 1995.
Much of the U.S. and Central America will experience a partial eclipse of the Sun this afternoon! Check the animated map below to see what time your location will be favored. If you do go out to look, be sure to use special glasses made to view the Sun.
