Multi-day Precursors to Prominence Eruptions
Abstract
Prominence eruptions are highly correlated to CMEs, and a better understanding of them would enhance the ability to forecast hazardous space weather. Increases in absorption, strong flows, cavity expansion, low-level heating, and photospheric flux cancellation have all been found prior to eruptions. Our recent research has analyzed most of these properties simultaneously and found that they are related, and they collectively start a day or more prior to eruption onset. These findings can be used to predict extended windows in which a prominence eruption is unlikely to occur.
