2005/04/20 (Wednesday)

03:26 UT  E Limb	In the aftermath of event reported to start at 22:06 UT
			on previous day, a faint and expanding ragged loop
			front develops.

05:26 UT  S West	Extremely faint reconexion event at PA ~ 236 (around
			3.8 solar radii). Due to its faintness, it is difficult
			to give an exact time of first appearance. The infalling
			feature is barely discernible. The outward moving one
			fades throughout C3.

08:26 UT  W Limb	Diffuse and faint spray-like front. It fades close
			to the inner edge of C3.

11:26 UT  E Limb	Extremely faint and diffuse front that quickly fades.

2005/04/21 (Thursday)

00:06 UT  W Limb	Very diffuse and ragged front precedes the development
			of a bright and ragged loop front (a little bit to S)
			that starts at around 00:26 UT. By 03:26 UT a thin and 
			bright feature can be discerned in the trailing material.
			
Time of the last C2 image analized: 12:26 UT.
