2005/12/09 (Friday)

	  S West	Gusty outflow along a streamer all along the day.

14:00 UT  S East	Faint and elongated loop front. It fades throughout C3.

	14:36 - 16:48 UT	LASCO data gap (C2 time).

21:36 UT  E Limb	Diffuse loop front that fades throughout C2.

2005/12/10 (Saturday)

	  N West	Very slow development of a system of faint loops -1-
			since late on previous day (difficult to give an exact
			time of first appearance). A narrow and apparently 
			elongated and circular structure starts to be discernible
			by the end of the day. The event will result in a 
			streamer blowout clearly seen in C3 on next day by 
			around 10 UT.

00:12 UT  N West	Diffuse front superposed in the LOS with -1- (see 
			previous entry) and moving faster.

19:36 UT  W Limb	Top of a loop front just appearing preceded by a 
			diffuse brightening. It develops as a big and twisted
			expanding structure.

2005/12/11 (Sunday)

	  N West	Several small reconection type events during the day,
			along the thin current sheet left behind the event
			described at the very beginning of previous day.

11:36 UT  WS West	Elongated and ragged loop front in the trailing material
			of event reported to start at 19:36 UT on previous day.
			It is followed at 17:00 UT by another elongated 
			structure.

16:24 UT  S West	A small and ragged blob-like front develops as a 
			twisted (circular) structure in the C2 FOV, just a 
			little bit to S of event reported to start at 17:00 UT
			- see previous entry - (and moving more slowly).

17:24 UT  EN East	Diffuse brightening precedes the development of a
			loop front. A twisted (rather circular) structure
			follows by 18:00 UT, developing more slowly.
