H alpha Prominence Event List [Aug/1998]
[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
- C1: break and slip down after slow rise
- C2: fade out or fall down with no rising motion
D. partially-activated prominence; partially brightening, or breaking down
of a pre-existing prominence
E. loop prominence
- E1: a loop top brightening followed by a single loop formation
- E2: post-flare loops (growing multiple loop system)
- E3: a growing bright mound or compact loop cluster
F. others
- F1: stable but exceptionally large prominence or in extraordinary shape
