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:

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.

HAO / MLSO is now providing daily composite images of the solar corona as seen from 3 viewing angles: STEREO B, Earth-Sun, and STEREO-A. The STEREO A/B composites consist of SECCHI images from: EUVI (inner corona seen against the solar disk), the MLSO MK4 K-Coronameter (blue), the COR1 Coronagraph (green) and the COR2 Coronagraph (in red). The SOHO/MK4 composite combines EIT (solar disk), MK4 (blue) and LASCO C2 (red). MK4 images are NOT rotated to match the STEREO viewing angles.
