LASCO Activity Report for
August 30, 2004 SOHO Science Daily Meeting
Planner: K. Schenk, G. Stenborg
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
2004/08/27 (Friday)
01:54 UT S East Extremely narrow and elongated expanding loop front at
the PA of the southern leg of event reported to start at
20:58 UT on previous day.
09:06 UT W Limb Bright loop front, cavity and twisted inner core. Typical
3-part structure CME. Gusty outflow and gusty
infalling material well into next day.
10:30 UT E Limb Faint assymetric front becomes discernible, developing
toward ENE.
13:54 UT S East Very faint front develops as an elongated loop. By
17:30 UT, a little bit to N, another front becomes
discernible. And by 18:30 UT, still a little bit to
N, a front smilar to the first one starts developing
at about 2 solar radii. Infalling material afterward.
They all fade throughout C3.
23:30 UT EN East Very faint small front develops as a ragged loop front
that fades close to the inner edge of C3.
2004/08/28 (Saturday)
12:06 UT W Limb Faint fan-like front. It fades throughout C2.
20:58 UT ENE-N East Very faint ragged front that quickly fades.
2004/08/29 (Sunday)
02:30 UT W Limb Bright ragged loop front followed at 03:54 UT by a
faint loop front that quickly fades. Bt that time,
just behind the bright front, a narrower ragged loop-
like structure can be discerned (already close to the
outer edge of C2 FOV). They both fade throughout C3.
04:30 UT S East Very faint jet-like front, apparently followed by
extremely faint expanding curved structures developing
toward the S Pole.
13:31 UT S East Another jet-like front that quickly fades. Afterward
(difficult to give an exact time of first appearance),
again a system of extremely faint expanding curved
structures develop toward the S Pole. They are barely
visible in C3.
2004/08/30 (Monday)
03:54 UT W Limb Ragged loop front that fades close to the inner edge of
C3. By 05:54 UT another ragged loop front follows. By
07:31 UT, a narrow and faster loop front follows to N.
Another (fainter) ragged front at 09:06 UT (it quickly
fades).
