Points Of Interest
2007/08/08 (Wednesday)
04:54 UT E Limb Slow development of a system of faint loop fronts.
Difficult to give an exact time of first appearance.
By midday, the development of a big twisted structure
can be observed. WIDTH in C3 at 02:18 UT (the next
day): ~ 55 deg.
03:30 UT WN West Faint loop front starts to be discernible (blob-like
top). It becomes brighter close to the outer edge
of the C2 FOV.
04:54 UT W Limb Very ragged front. It fades in C3, rather close to
its inner edge.
08:06 - 10:06 UT LASCO Data Gap (c2 time).
17:07 UT W Limb Veru faint, thin and elongated loop front followed
by another one (slightly brighter) at 18:31 UT. They
both fade throughout C2.
