	  S East	Gusty outflow.

04:54 UT  W Limb	Ragged front developing toward SW, preceded by a couple
			of jets at 20:54 (previous day) and 00:30 UT, and a 
			faint spray front at 04:30 UT. It is followed at 
			07:54 UT by another (narrower) ragged front.

07:31 UT  E Limb	Another faint narrow and diffuse loop front developing
			toward NE.

16:30 UT  N West	Bright loop front, cavity, and core. Twisted trailing
			material. By ~ 13:25 UT EIT Fe XII images show the
			starting of a filament eruption, part of which is 
			located slightly SW of NOAA AR 0572, very close to the
			limb; the rest of it, seems to extend up to behind the 
			limb. By 18:30 UT very faint extension begin to be
			discernible over the C2 SW limb, and S Pole up to the 
			S East limb. Possibly 'shock' signature if related to 
			the event.

18:48 UT  S East 	By 18:48 UT EIT Fe XII running difference images begins
			to show the development of a CME coming out from just
			behind the SE limb. No clear signatures of the event 
			can be discerned in C2, except for the gusty outflow
			and a faint elongated loop barely discernible at
			~ 19:54 UT, already in progress.

23:30 UT  N West	Bright narrow and elongated ragged loop front. Gusty
			outflow into next day. By ~ 22:36 UT Fe XII running
			difference images show an extremely faint signature 
			of a CME coming out apparently from behind the NW limb.
