LASCO Activity Report for
March 10, 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
2004/03/09
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 developing toward S. 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.
Gusty outflow follows.
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.
12:06 UT S West Faint narrow ragged front. It fades throughout C2.
17:30 UT S East Bright ragged loop front and cavity. Trailing part not
discernible due to event reported to start at 22:30 UT.
Starting at ~ 16:24 UT EIT Fe XII running difference
images show CME coming out from just behind the SE limb.
20:00 - 21:30 UT Data Gap (ICAL01: Intercalibration EIT/CDS)
21:30 UT N East Bright loop front, cavity, and twisted trailing
material. Typical flux-rope event. Starting at
~ 21:24 UT (after data gap) EIT Fe XII running
difference images show CME coming out from behind the
NE limb.
22:30 UT S East Bright loop front evolving almost in parallel with
previous event. C3 images show the event to be slightly
slower than the previous one. Difficult to give accurate
time of first appearance due to event reported to start
at 17:30 UT. No signatures in EIT Fe XII running
difference images.
22:30 UT N West Slow development of a narrow system of loops develops
as a twisted structure into next day.
2004/03/10
05:54 UT W Limb Ragged front. Infalling material starting at ~ 04:35
solar radii (08:54 UT).
09:06 UT S East Likely streamer blowout, preceded by the slow
development of a loops' system. Starting at around
09:00 UT EIT Fe XII running difference images show
CME coming out from just behind the SE limb.
14:25 - 19:05 UT Temporary DSN Data Gap
