LASCO Activity Report for
February 21, 2002 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

None today.


2002/02/20

00:30 UT  E Limb	Narrow spray

02:30 UT  N East	Faint ragged front along faint streamer. 
			Brighter fronts follow

03:30 UT  N West	Fairly wide bright asymmetric loop front with 
			some core-like and trailing material. 
			M4.2 flare in AR 9825

06:30 UT  W Limb	Wider, brighter and faster loop front than previous 
			event with clear cavity and core. Very faint 
			extensions around significant portion of disk.
			M5.1 flare in AR 9825

08:54 UT  S East	Very faint blob

10:30 UT  N West	Ragged loop front disintegrates through C2. Some
			dispersed core-like material and other trailing
			material. M4.3 flare in AR 9825

12:54 UT  N East	Very faint narrow front/spray along faint streamer

16:30 UT  N East	Faint nebulous front followed by system of loops 
			and loop fronts initiating major partial streamer
			blowout, possibly complete blowout. Slow event 
			still in progress

17:54 UT  N West	Ragged loop front with bright core. Similar to
			03:30, 10:30 events, perhaps slower. M3.5 flare
			AR 9825?

17:54 UT  S West	Very narrow loop front, quite fast

21:30 UT  S West	Faint loop front, fairly wide, fades through C2.
			M2.4 flare AR 9830. Further faint fronts follow 
			into next day.

2002/02/21

03:06 UT  N West	Very narrow bright blob-like ejection, possible
			dense region at top of narrow loops. Quite slow	

05:30 UT  N West	Fairly wide bright asymmetric loop front. S edge
			obscures previous event, maybe accelerates. Some
			continued outflow epecially in S

06:54 UT  S West	Moderately wide loop front with cavity

12:54 UT  N West	Ragged loop front with cavity and core, some 
			continued outflow, M3.9 flare in AR 9825 peaks
			in EIT at 12:24

12:54 UT  S East	Somewhat narrower loop front with significantly
			less trailing material. Faster than NW event, 
			narrow CME in EIT peaks in absorption at 12:36 
			from new AR
