Points Of Interest
2006/12/22 (Friday)
No significant activity.
2006/12/23 (Saturday)
08:30 UT E Limb A very faint (apparently) twisted structure starts
to be discernible. It is difficult to give an exact
time of first appearance. It fades throughout C3.
2006/12/24 (Sunday)
15:30 UT S Pole Brightening over the S Pole develops as a wide ragged
loop front (almost Partial Halo in the C2 FOV) followed
by some faint expanding loop fronts. The wide ragged
loop front is first seen in C3 at 17:18 UT developing
toward SSE. The angular span of the event in C3 by
20:18 UT is about 100 deg (from about PA 120 to 220).
Afterwards, the event gradually fades. By the end of
the day it is no longer discernible (LE around midway
to the end of the C3 FOV). GOES reported NO X-ray
events during the day (X-ray activity below the A-level.
21:30 UT E Limb Ragged front that fades close to the inner edge of C3.
2006/12/25 (Monday)
06:30 UT E Limb Not-well-defined front that quickly fades.
08:30 UT S Pole Elongated blob-like front followed by some gusty
outflow.
19:31 UT S Pole Jet-like front.
2006/12/26 (Tuesday)
05:54 UT E Limb Diffuse and very faint loop-like front.
