Points Of Interest

2006/11/03 (Friday)

01:31 UT  N West	Blob-like front starts to be discernible. It fades 
			throughout C3.

03:08 UT  E Limb	Faint and very diffuse loop-like front.

07:31 UT  E Limb	Elongated and diffuse loop-like front. It fades 
			throughout C3.

12:06 UT  E Limb	Elongated and diffuse loop-like front (brighter than
			the two previous events).  It fades throughout C3.

19:31 UT  N East	Very bright and big loop front with diffuse extensions
			that span up to past the N Pole. LE already midway
			to the end of the C2 FOV. Only one C3 frame captured 
			the event (19:42 UT). No significant X-ray activity
			was recorded by GOES by the time (B-class). EIT 195
			running difference images do show signatures of a 
			rather important backsided event all above the NE 
			limb starting at  19:13 UT. Development missed in the
 			following data gap.

	20:21 - 24:00 UT 	NO LASCO CME watch due to special observation
				program for Mars Express and Venus Express
				Campaign.

2006/11/04 (Saturday)

01:31 UT  E Limb	Fast fan-like front. It fades close to the inner edge
			of C3.

	09:00 - 11:30 UT 	LASCO Data Gap (C2 time) due to EIT 
				sector wheel hang.

13:31 UT  E Limb	Bright elongated ragged loop front. Development missed
			in the following data gap.

	14:30 - 24:00 UT 	NO LASCO CME watch (C2 time) due to LASCO 
				special program: polarization sequences.

2006/11/05 (Sunday)

05:54 UT  N Pole	Jet-like front.

11:06 UT  E Limb	Elongated front preceding a slightly brighter elongated
			front (12:06 UT), which in turn precedes an even
			brighter ragged loop front (14:06 UT).

13:54 UT  W Limb	Very faint and not-well-defined front that fades
			throughout C2.

15:30 UT  E Limb	Another elongated ragged front. It quickly fades.

17:30 UT  E Limb	Bright narrow front develops as a big and very bright 
			loop front by 17:54 UT. At this time the LE on E is
 			already past the outer edge of the C2 FOV. Faint and
 			diffuse extensions develop up to past the N Pole. By
			18:54 UT the diffuse extensions seem to cover the C2
 			occulting disk. The event was first seen in C3 at 
			17:42 UT as a narrow front just showing up above the
			E Limb. By 18:18 UT, a wide and bright loop front 
			spans all above the NE limb, with faint extensions up
			to past the N Pole. Signal too faint to be discernible
			on the S Pole. The mean plane-of-sky speed of the LE
			at PA ~ 70 was ~ 1520 km/sec. No significant X-ray 
			activity was detected by GOES related either in time 
			or space to this event. Just for completeness, there 
			was a C3.7 X-ray flare on NOAA AR 10921 (S06W13)
 			between 12:16 - 12:340 UT with peak emission at 
			12:40 UT. Likewise, EIT 195 images do not show
 			significant frontsided activity related to the event,
 			although they do show a rather important backsided 
			CME event all above the NE Limb starting at around
 			17:24-17:36 UT. A wave can be seen developing coming
	 		from behind the E limb starting at 18:42 UT. The 
			event has therefore been determined as an at least
 			partial halo event backsided.
	
	20:21 - 24:00 UT 	NO LASCO CME watch due to special observation
				program for Mars Express and Venus Express
				Campaign.

			data gap.

			data gap.

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