Points Of Interest
Venus entered the C3 FOV from the right on 2005/02/26 (by the end of
the day).
Kreutz comet starts to be seen on C3 on 2005/02/26 at around 15:42 UT,
moving from the bottom left corner (SE) toward the center of the image.
It vanishes by 2005/02/17 at around 17:18 UT.

Mostly quiet.
2005/02/26 (Saturday)
09:30 - 11:54 UT Temporary Data Gap.
15:30 UT N Pole Faint and diffuse loop front that quickly fades.
Otherwise, mostly quiet.
2005/02/27 (Sunday)
10:34 UT W Limb Bright loop front followed at 11:06 UT by another
loop front, which precedes a twisted structure (inner
core). The second loop front and twisted structure
develop more slowly than the outer loop front. They
all develop toward WSW-SW.
18:30 UT N East Jet-like front.
21:30 UT ES East Bright and ragged loop front, preceded by a diffuse
front that starts to be discerned as early as 19:54 UT.
Trailing material.
22:30 UT N East Another jet-like front.
2005/02/28 (Monday)
00:54 UT N East Jet-like front that quickly fades.
