A quiescent prominence typically lasts about a month and may erupt in a Coronal Mass Ejection (CME)
Why the adjective "quiescent"? I assume not all prominences result in a CME, right? Do non-"quiescent" prominences end in CMEs more or less often than "quiescent" ones? And, what even does "quiescent" mean here? One in a less active state after beginning in a more active state?
"Quiescent" in this context is just the label used for prominences that are stable for days or weeks, rather than the time scale of hours with "active" prominences. Quiescent prominences may or may not evolve to active ones that can produce eruptions.
Ah, thanks. And I supposed active, shorter lived prominences can also produce CMEs (or not) just as often (or not) as quiescent ones?
