Although our prediction was designed to predict the steady or slowly evolving structure of the solar corona, there is no guarantee that the Sun will cooperate during the eclipse!
During our preparation for the energization, we noticed a nice prominence eruption near the east limb on October 23, 2020 around 14UT. This event, which produced a Coronal Mass Ejection or CME, originated from an active region that would have been present just off the limb for the eclipse view.
The movies above show an animation of our Preliminary Prediction model with this region over-energized. Each frame in the animations is approximately 10 minutes.
While this produced a nice CME in our preliminary model, we did notice that this area of the sun remained quite energized in the following rotation, including a slow liftoff/eruption on November 21, 2020. If a CME happens around eclipse time, either here or somewhere else, we just might catch an important part of its evolution!
