LASCO Activity Report for
March 09, 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
2004/03/08
S East Gusty outflow all along the day.
00:30 UT S Pole Very faint ragged loop front. Outflow afterward. B8.4
X-ray flare on NOAA AR 0567 (S14E62) at 23:03 UT on
previous day (peak). More B-class X-ray flares on the
same region at 07:30 and 08:20 UT. Large and faint
extensions over NW. Difficult to establish whether
they have any conexion to the event.
02:54 UT W Limb Extremely narrow ragged front followed at 06:30 UT by
another ragged front. They fade throughout C2.
06:54 UT W Limb Very faint loop front extending over SW (central axis
at PA ~ 245). Between 05:36 and 09:38 UT, EIT Fe XII
show the development of a CME originating on NOAA AR
0569, which is located slightly W of the central
meridian (~20 deg) at about 11 deg S latitude.
23:06 UT W Limb Ragged asymmetric front.
2004/03/09
00:06 UT N West Faint narrow ragged front. It fades throughout C2.
00:54 UT S West Faint and diffuse elongated front preceding several
faint and diffuse 'half' loop fronts starting at
~ 04:06 UT. Signatures compatible with the above
description in EIT Fe XII running difference images,
coming out from behind the SW limb.
01:54 UT S East Bright ragged loop front. It fades throughout C3.
01:54 UT W Limb Jet-like front followed at 03:54 UT by another one. At
06:30 UT follows an initially small ragged front that
develops as a fairly faint loop front (barely visible
in C3).
10:54 UT W Limb Narrow ragged front.
12:20 - 19:00 UT Temporary DSN Data Gap
