LASCO Activity Report for
February 22, 2005 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





2005/02/18 (Friday)

	Note: 	Multiple B- and C-class X-ray flares from NOAA AR 10732 all 
		along the day (around N14W90).

04:30 UT  S Pole	Diffuse jet-like front.

18:06 UT  E Limb	Diffuse and not-well -defined front that fades 
			throughout C2, superposed in the LOS with the 
			development of a system of loops (the system of loop
			starts to be discerned at ~ 17:30 UT).

20:54 UT  S West	Bright and ragged loop front immediately followed 
			by another loop front. Apparently, after the
			appearance at 22:30 UT on W of a faint and diffuse 
			loop front, a diffuse and expanding loop front 
			develops on SW. 

2005/02/19 (Saturday)

	Note: 	Still multiple B-class X-ray flares from NOAA AR 10732 until
		around midday.

	01:42 - 05:18 UT	Temporary C3 Data Gap.

04:30 UT  S West	Expanding loop fronts all above the W-SW-S limbs.

11:06 UT  W Limb	Very bright loop front with structured interior. Some
			infalling blobs in the trailing material. Gusty 
			outflow. GOES recorded an M3.3 X-ray flare from NOAA 
			AR 10732 (N12W90) between 10:36 - 11:13 UT with peak
			emission at 11:01 UT.	

22:30 UT  W Limb	In the aftermath of previous event, elongated ragged
			front that fades throughout C3.

2005/02/20 (Sunday)

04:06 UT  W Limb	Ragged blob-like fronts with some infalling material.

	14:54 - 18:30 UT	Temporary Data Gap.

18:30 UT  W Limb	Lots of small reconexion events in the apparent 
			trailing material of a potential event which could 
			have occurred during data gap.

18:30 UT  E Limb	Bright ragged loop front already under development
			after data gap. 

19:31 UT  NN West	Small loop front that quickly fades.

2005/02/21 (Monday)

	Note: US federal Holiday --> President's Day.

	  W Limb	Gusty outflow all along the day.

	21:36 - 00:00 UT	Temporary Data Gap.

2005/02/22 (Tuesday)

10:54 UT  WN West	Bright and extremely elongated loop-like structure.
