Points Of Interest
2004/02/24
02:30 UT N Pole Extremely faint front (difficult to determine exactly
time of first appearance). Expansion to NW. 'V-shaped'
feature in C3 (09:18 UT), fading out throughout C3.
08:06 UT W Limb Narrow ragged loop front, not discernible in C3.
12:30 UT E Limb Very narrow ragged front developing towards SE. In C3
barely visible only close to the inner edge.
13:31 UT W Limb Bright spray-like front.
15:30 UT S West Bright loop front, cavity, and twisted inner structure,
slightly to S of previous event.
20:06 UT N East Faint spray-like front. It fades throughout C2.
2004/02/25
00:05 UT S West At the same PA as event on previous day at 15:30 UT,
an apparently faster faint front develops, while the
inner structure of that previous event is still under
progress in C2 FOV, making it a complex event.
Difficult to give an exact time of first appearance.
02:30 UT N Pole Extremely faint elongated loop front developing toward
N West.
