Points Of Interest

2005/07/05 (Tuesday)

	
	  EN East	The slow development of a system of faint loops that 
			started at 19:54 UT on previous day, continues. Since
			late on previous day, development of a bright twisted
			structure.

03:30 UT  WS West	Faint, diffuse, and wide expanding loop front superposed
			in the LOS with the twisted trail of event reported to
			start at 06:30 UT on previous day. It is followed by
			a similar one at 04:06 UT, which apparently merges then
			with a next one that starts to be seen at ~ 04:54 UT.
			This whole event surpasses, while in the C3 FOV, the
			event reported to start at 06:30 UT on previous day.

15:30 UT  S East	Bright loop-like front with apparently extremely faint
			extensions above the S Pole. By 15:54 UT, an apparent
			distinct front can be discerned behind, developing 
			mainly toward E. By this time on, the faint extensions
			mentioned above extend up to the W Limb, becoming
			brighter there. There is a small C2 data gap after
			16:30 UT, the next C2 image available corresponding to
			18:06 UT. At that time, very faint extensions can 
			already be seen above the N Pole. The event was first
			seen in the C3 FOV at 16:18 UT, above the SE limb,
			with very faint extensions developing above the S Pole. 
			A second front is clearly visible above the E Limb by
			17:42 UT. By 19:42 UT, the C3 occulting disk appears
			completely covered. The mean plane-of-sky of the LE 
			of the two main features mentioned above is given 
			below (based on C3 data): i) Outermost front at PA 125:
			794 km/sec; ii) Second front at PA 085: 654 km/sec.
			GOES reported a C1.3 X-ray flare on NOAA AR 10788
			(S10E33) between 14:52 - 15:49 UT with peak emission 
			at 15:26 UT. EIT 195 running difference images show 
			a relatively strong brightening on AR 10788 at 15:24 UT,
			which was preceded by signatures of a CME developing 
			toward SW since 15:00 UT. EIT 195 images show, i) the
			eruption of a small filament atop the AR starting at
			~ 14:24 UT, and ii) the dimming of a region to S-SW of 
			the AR starting at 15:00 UT. In summary, the event has
			therefore been determined as a faint and asymmetric 
			full halo event, frontsided, associated to a filament
			eruption and C-class X-ray activity on NOAA AR 10788.

21:12 UT  W Limb	Diffuse front that quickly vanishes precedes the slow
			development of a faint and asymmetric loop front
			early on next day.

00:30 UT  E Limb	Small blob-like feature precedes a bright and ragged
			loop front. Gusty outflow on ENE.  

Time of the last C2 image analyzed: 12:06 UT.
