Quick Summary

A transient solar prominence is a dynamic eruption of incandescent, ionized gas from the Sun's chromosphere into its corona. Unlike Earth's clouds, these solar phenomena are supported by magnetic fields. They are a key part of solar activity and can manifest as sprays or surges, often associated with solar flares. These eruptions eject material at high speeds and can cause shock waves in the corona, known as coronal mass ejections, which can impact Earth's magnetic field. Transient prominences are distinct from quiescent prominences, which are longer-lived and associated with large-scale magnetic fields.12

…are of two main types, active and quiescent. Active prominences erupt quickly and have lifetimes lasting from several minutes to a few hours. They are associated with sunspot groups and, like these, are correlated in numbers and activity with the solar cycle. Quiescent prominences tend to emerge smoothly and subside…
