LASCO Activity Report for
August 31, 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
2004/08/30 (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). Gusty emission afterward. GOES recorded a C2.4
X-ray flare from NOAA AR 10663 (N06W66) between 03:04 -
03:18 UT with peak emission at 03:11 UT. And several
B-class flares from the same active region between
09:54 - 15:04 UT (peak emissions at 10:00, 14:03, 14:52,
and 15:02 UT).
16:54 UT W Limb Another ragged loop front that fades throughout C3.
Event most likely related to activity on NOAA AR 10663.
18:06 - 19:55 UT LASCO Data gap (C2 time).
20:54 UT W Limb Another ragged loop front followed at 21:54 and 23:30 UT
by a couple of similar ragged fronts. They all fade
throughout C3. Events most likely associated with
activity on NOAA AR 10663. Please also note that GOES
recorded a C1.0 X-ray flare from NOAA AR 10663 (N04W78)
between 18:06 - 18:29 UT with peak emission at 18:18 UT
(possible C2 event associated to the X-ray event likely
missed in the data gap).
23:06 UT NN East Very faint and diffuse asymmetric front. Barely visible
in C3.

01:31 UT W Limb Another ragged loop front. GOES recorded a B9.3 X-ray
flare from NOAA AR 10663 (N03W83) between 00:40 -
00:52 UT with peak emission at 00:46 UT.
05:54 UT W Limb Bright loop front with structured interior. GOES
recorded an M1.4 X-ray flare from NOAA AR 10663
(N06W82) between 05:24 - 05:47 UT with peak emission
at 05:38 UT.
08:00 - 15:45 UT Temporary DSN Data Gap.
