Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.
Points Of Interest
2005/02/11 (Friday)
WS West Since early in the day, very slow development of a
system of faint loops along the streamer. It continues
well into next day.
00:30 UT WS West Faint and elongated feature barely N of streamer.
Barely visible in C3.
02:54 UT ES East Bright ragged front with structured interior.
12:06 UT ES East Another bright ragged front with structured interior
and trailing material. By ~18:54 UT, some small
ragged fronts superposed in the LOS with the trailing
material.
12:54 UT N Pole Diffuse jet-like front developing slightly toward NNE.
It quickly fades.

01:31 UT ES East In the trailing materila of event reported to start
at 12:06 UT on previous day, an elongated curved
feature starts to be discernible (apparently northern
leg of a loop front that fades close to the inner
edge of C3).
05:54 UT S East Small ragged front becomes discernible in the trailing
material.
12:06 UT WS West A faint loop front becomes discernible in the slow
development of a system of loops along the streamer
that started on previous day. It fades throughout C3.
16:54 UT WS West Another faint loop front (little brighter than previous
one), immediately followed by a kind of reconexion
event.
18:06 UT WN West Very diffuse and extremely faint elongated loop front
that fades throughout C2.
18:30 UT S Pole Very diffuse and faint elongated loop front that
fades throughout C2.
23:54 UT N West Jet-like front that quickly fades.
2005/02/13 (Sunday)
00:06 - 03:30 UT Temporary Data Gap.
06:54 UT SS West Very diffuse and faint elongated loop front that
fades throughout C2.
11:30 UT S East Complex Partial Halo Event. GOES reported a C2.7
X-ray flare on NOAA AR 10733 (S11E09) between 10:28 -
10:51 UT with peak emission at 10:40 UT. EIT 195
running differences images show a brightening on the
aforementioned AR at 10:38 UT followed by an intensity
disturbance (wave) toward W - SW - S - SE of the AR,
stronger toward S and SE.
11:30 UT W Limb Very faint and diffuse front that fades throughout C3.
2005/02/14 (Monday)
E Limb Slow development of a relatively wide system of loops
since late on previous day.
06:06 UT W Limb Very faint and diffuse loop front apparently preceded
by an even fainter front that spans all above the SW
limb.
