LASCO Activity Report for
March 29, 2001 SOHO Science Daily Meeting
Planner: K. Schenk, G. Lawrence
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.

None today.
2001/03/28
00:06 UT S East Bright elongated ejection along faint streamer
01:27 UT HALO Thin bright well defined front over E Limb
and S East becomes full halo in C2 by 02:06
and C3 by 02:42. Plane of sky speed in S East
is ~420 km/s. Backsided filament eruption.
Typo in start time during yesterday's report.
03:50 UT W Limb Narrow thick bright front along faint streamer.
Cavity follows
05:26 UT N East Initially bright front fsdes in C2. Slow with
cavity and faint arcades following
12:50 UT HALO Bright event initially over S Pole but full halo
in C2 by 13:27. Two bright clear well-defined
fronts in S (two peaks to GOES events) with
fainter extensions around rest of occulting disk.
530 km/s through C2. M4.3 in AR 9393.
22:26 UT S East Narrow jet along streamer
23:26 UT N West Faint fan

00:26 UT S East Wide bright ragged front fills quadrant.
Gusty outflow follows.
03:26 UT N West Faint slow loop/front, widens in C2
10:26 UT HALO Very bright narrow front in N West is full
halo CME in C2 by 10:50 UT and 11:18 in C3.
Cavity and arcades in N West by 11:26 (C2).
Plane of sky speed 991km/s with deceleration.
