Points Of Interest
2005/01/31 (Monday)
S West Gusty outflow in the form of small ragged fronts, all
along the day.
07:31 UT S East Big and bright loop front. By 07:54 UT, the northern
leg of the loop reaches the ENE Limb. Trailing material,
gusty outflow afterward in the form of brigh and small
fronts along a current sheet. First seen in C3 at
07:42 UT. Faint and diffuse extensions discernible in
C3 over the S Pole. Starting at 06:36 - 06:48 UT, EIT
195 running difference images show a big CME on SW,
apparently originated on the back side.
10:30 UT S West In the gusty outflow, an elongated and ragged loop
front is discernible. It fades throughout C3.
18:30 UT E Limb Very faint and diffuse expanding ragged front that
fades close to the inner edge of C3.
23:54 UT W Limb Spray-like front developing slightly toward WNW. It
fades throughout C3.

06:06 UT N West Very faint blob-like front starts to be visible at
~ 4.69 solar radii (PA ~ 315). An infalling structure
can be seen by the time, a little bit to N.
11:06 UT N East Very big and bright loop front. By 11:30 UT, faint
and diffuse extensions surround completely the C2
occulting disk. First seen in C3 at 11:18 UT. Starting
at 10:36 UT, EIT 195 running difference images show
a wide CME above the E - NE limb, originated on the
back side.
12:06 - Present (~ 16:00 UT) Temporary Data Gap.
