LASCO Activity Report for
March 15, 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
2004/03/12
S East Gusty outflow all along the day.
00:30 UT N East Developing of an asymmetric loop front. Small ragged
fronts during the day.
00:30 UT N West Extremely faint diffuse front moving faster that a
bright ragged front following at ~ 01:31 UT. Due to
the superposition of both events on the line of sight,
it is difficult to give an accurate time of first
appearance for the second event. EIT HE II images show
the eruption of a a huge prominence coming out from
behind the NW limb (first seen at 19:19 UT on previous
day, next image at 01:19 UT). Huge twisted structure
follows.
05:30 UT N East Faint ragged loop front at PA of the southern leg of
the asymmetric loop front reported to start at 00:30 UT.
08:30 UT N East Blob-like front at PA of the event reported to start
at 00:30 UT.
16:54 UT W Limb Faint ragged loop front developing towards NW. At
~20:06 UT follows blob-like front slightly to N,
starting at roughly 4 solar radii.

S East Gusty outflow all along the day.
08:06 UT S West Extremely faint ragged loop front. It fades in C2.
2004/03/14
02:06 UT W Limb Extremely faint and small blob-like front going outward
and small feature falling down. Starting point at
~ 4.30 solar radii (PA ~ 263 deg). It is followed at
~ 09:06 by an extremely faint ragged front.
03:54 UT N East Couple of very faint ragged loop fronts, one developing
more toward N.
07:31 UT N Pole Jet-like front that quickly fades.
13:31 UT S West Narrow and diffuse front preceding asymmetric loop
front at ~ 15:30 UT.
2004/03/15
09:30 UT N West Ragged front.
12:55 - 21:30 UT Temporary DSN Data Gap.
