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

2006/11/06 (Monday)

00:42 UT  N East	Faint ragged front already under development after 
			data gap.

00:42 UT  S West	Faint ragged front already under development after 
			data gap.

04:06 UT  E Limb	Bright fan-like front.

10:30 UT  E Limb	Bright elongated loop front.

14:30 UT  E Limb	Diffuse loop-like front. It fades throughout C2.

17:54 UT  N East	Very bright front. Diffuse loop-like extensions 
			develop to N, spanning across the N Pole by 18:06 UT.
 			These diffuse extensions surround the C2 occulting 
			disk by 18:54 UT (bulk of the CME already well past 
			the outer edge of the C2 FOV on E, signal on SW barely
 			above the occulting disk). The event is first seen 
			in C3 at 18:42 UT, the bulk of the CME heading toward 
			NE and very bright, the loop-like extensions already
 			covering all above the N Pole. The C3 occulting disk 
			is fully surrounded by the loop-like extensions by 
			21:42 UT. By that time, the LE of the bulk of the 
			event on NE already reached the end of the C3 FOV. 
			The mean plane-of-sky speed of the LE at PA ~ 72 deg 
			was ~ 1995 km/sec (based on C2 and C3 data). GOES
 			recorded a C8.8 X-ray flare on N00E89 between 17:43 -
 			18:06 UT with peak emission at 17:46 UT. EIT 195 
			images show signatures of a big CME all above the E 
			and NE limb starting at 17:36 - 17:48 UT. The source 
			of the CME is in the backside, apparently barely 
			behind the E Limb. A wave follows, covering as it
 			develops most of the E part of the disk. In summary, 
			the event has therefore been determined as a very
 			asymmetric full halo, associated to a close-to-limb
 			backsided event. Important wave signatures associated 
			to the event could be seen all across the eastern 
			part of the disk (in other words, be aware of the 
			flank of the event). 

2006/11/07 (Tuesday)

00:54 UT  E Limb	Initially bright loop front. GOES recorded a C1.2 
			X-ray flare on N)!E89 between 00:24 - 00:41 UT with
			peak emission at 00:51 UT.

04:54 UT  EN East	Elongated loop front. It fades throughout C3. 'Pair
			formation' just a little bit to S and small ragged
			fronts in the trail and to N by 07:31 UT.

Last C2 image available by the time of writing:  12:54 UT.
