[Classification of Active Prominence]
A. surge type; jet-like ejection
(Most of the ejected plasma returns back to the solar surface along
a magnetic line of force.)
- A1: flow back along the ejection pass
- A2: flow down to the other foot point over the apex of a loop
B. eruptive prominence type; high-speed eruption of a pre-existing prominence
- B1: gradually accelerated to the escaping velocity
- B2: explosively accelerated to the escaping velocity (spray type)
C. disruptive prominence; disintegration of a pre-existing prominence
