LASCO Activity Report for
September 25, 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.
An archive of these reports is available.


Points Of Interest

Data badly degraded due to ongoing proton storm


2001/09/21

17:30 UT  S West	Ragged front along streamer followed by slow 
			loops and some arcades

2001/09/22

06:06 UT  W Limb	Initially narrow bright front widens through C2.
			Numerous arcades follow

10:34 UT  N West	Fairly wide bright front with fainter extension
			over N Pole. Some gusty outflow in N West

18:30 UT  W Limb	Bright front, part of residual outflow from
			06:06 event? Similar speed

2001/09/23

12:06 UT  N East	Bright ragged front along streamer follows 
			slow loops

13:30 UT  S East	Sequence of faint loop fronts, also narrow 
			loops to N

14:30 UT  E Limb	Bright loop front, quite fast, with small
			bright kotted core
		
17:06 UT  S Pole	Faint loop front over S Pole. These last four
			events create impression of a wide slow	
			partial halo but some are backsided

20:30 UT  HALO		Bright front over W Limb had fainter extensions
			around disk and is a full halo event by 21:30
			and possibly at 20:30, hard to tell amongst
			earlier outflow. Fastest in N and much faster
			than earlier events. Most probably backsided

21:54 UT  S East	Fairly wide bright front maybe extends up to
			NE and SW. Hard to tell with all other outflow.
			Most probably backsided

2001/09/24

02:54 UT  W Limb	Faint loop front, another at 08:30

04:54 UT  N Pole	Very faint blob/narrow front

10:30 UT  HALO		Thick wide bright very fast front in S East
			is full halo CME by 10:54. Core-like material
			and some arcades follow in S East. Probably 
			associated with CME and subsequent X2.6 flare
			in AR9632 at S18E27
