LASCO Activity Report for
September 08, 2004 SOHO Science Daily Meeting

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.

Points Of Interest

2004/09/07 (Tuesday)

  	  S Pole        The slow and continuous development of a system of
			asymmetric loops that started at around 16:30 UT on
			previous day strongly continues at least during the 
			first half of the day, spanning all above the S Pole. 
			As time goes by, the main direction of the flow seems 
			to rotate toward W, like following the Sun's rotation.
			ACtivity most likely associated with the 'cluster' of
			active regions 10667, 10669, and 10670. 
		
08:30 UT  W Limb	Small and faint loop front that quickly fades. EIT 
			Fe XII running difference images show an apparently 
			barely backsided starting at around 07:36 above the 
			W Limb. GOES recorded a C1.1 X-ray flare form NOAA AR
			10668 (S08W88) between 07:06 - 08:03 UT with peak
			emission at 07:38 UT.

15:30 UT  E Limb	Bright and wide loop front with structured interior and
			trailing material and gusty outflow well into next day.
			By 16:54 UT an apparent different structure seems to
			develop inside the previos CME and spanning up to above
			the S Pole. The development of two different structures
			is clearer in C3. EIT Fe XII running difference images
			show a big and barely backsided CME above the E Limb
			starting at around 14:00 UT. Please also note that
			between 15:24 - 16:12 UT an intensity disturbance is 
			seen travelling all above the SE Limb (maybe related to
			the second feature seen in C2 FOV?).
			GOES recorded a long duration X-ray event, i.e., a 
			C2.8 X-ray flare from N03E85 between 13:40 - 16:43 UT
			with peak emission at 15:29 UT (not associated with a
			currently named NOAA AR).  

18:54 UT  S West	Diffuse and wide loop front. Continuos development of a
			system of loop fronts into next day. EIT Fe XII running
			difference images show a faint CME signature from nearby
			NOAA AR 10671 starting at around 18:12 UT. Post-event
			loops develop afterward.

	  E Limb	Intermitent small ragged fronts. GOES recorded a C1.5
			X-ray flare from N05E85 between 00:59 - 01:26 UT with
			peak emission at 01:10 UT.

02:30 UT  N East	Ragged and elongated loop front.

02:30 UT  S West	Superposed in the LOS with event at 18:54 UT on previous
			day a faint ragged front develops moving apparently 
			faster. More similar fronts afterward.

04:30 UT  S Pole	Faint and elongated front. GOES recorded a B9.0 X-ray
			flare from NOAA AR 10699 (S05E02) between 03:41 - 03:57
			UT with peak emission at 03:49 UT.
