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. In a lucky coincidence this also produced a nice CME in our model. Each frame in the animations is approximately 10 minutes. If a CME happens around eclipse time, we just might catch an important part of its evolution!
