Points Of Interest

	  S East	Event reported to start at 21:54 UT on previous day
			continues its development. Here is the corresponding
			entry to that event: 
		      -	Slow development of a wide and diffuse loop-like front
			first seen in C2 at 21:54 UT (on 05/01/10) above the 
			S East Limb, already under development after data gap
			between 18:30 - 21:54 UT. Bright structure inside. 
			Mean plane-of-sky speed of the outermost front (LE) 
			based on C3 data at PA 123: ~ 304 km/sec, slightly
			accelerated. As for the inner structure, its mean
			plane-of-sky speed at PA 123 was about 272 km/sec, 
			also slightly accelerated (though lower value than 
			that of the outermost front). Angular span of the 
			event at 09:18 UT (C3): ~ 100 deg, from PA 080 - 180.

01:31 UT  S West	Extremely faint small fronts start to be discernible in
			C2, already far from the inner edge. EIT 195 images
			show the eruption of a prominence between 22:24 - 23:36
			UT on SW, showing then continued outflow in emission
			until about 08:00 UT.

03:54 UT  N East	Faint and diffuse expanding loop front that fades
			throughout C3.

06:06 UT  W Limb	Faint loop front just appearing preceded by a another
			faint and not-well-defined front at ~ 03:54 UT.

06:06 UT  S East	Very faint and diffuse front superposed in the LOS with
			the aftermath of event reported to start at 21:54 UT
			on previous day. By 07:54 UT, a faint expanding loop
			front starts to be seen above the E Limb. It fades 
			throughout C3. Much gusty outflow to S, well into next
			day.	

09:30 UT  NN West	Couple of very faint front starts to be discernible. 
			They fade throughout C3. By 12:54 UT, infalling
			'v-shaped' structure (the event looks like a 'pair
			formation').

17:30 UT  NN East	Faint expanding loop front that fades throughout C3.
			Another one, fainter, on NNW apparently developing
			faster.

18:06 UT  E Limb	Faint and ragged expanding front. It also fades 
			throughout C3.

23:30 UT  S East	Faint and ragged expanding loop front, brighter to S.
			It fades throughout C3.

	  E Limb	Gusty outflow all across the eastern limb.
