02:12 UT  S West	Diffuse jet-like front.

13:00 UT  S West	Small blob-like front starts to be discernible
			(apparently as a result of 'pair formation'). Fainter
 			blob coming down).

17:00 UT  W Limb	Not well-defined-front, top of an apparently twisted
			structure that develops toward WSW. WIDTH in C3 at
			~ 21:42 UT: ~ 40 deg.

23:12 UT  NN West	Diffuse fan-like front (only seen in 1 frame).

23:12 UT  S West+	Diffuse jet-like front.

2007/03/10 (Saturday)

00:24 UT  W Limb	Ragged loop front in the trail of event rteported to
 			start at 17:00 UT on previous day. It fades throughout
 			C3. Gusty outflow. WIDTH in C3 at 04:18 UT: ~ 25 deg.
			Another fornt seems to follow by 03:48 UT, developing
			toward WNW.

14:12 UT  E Limb	Loop front starts to be discernible. WIDTH in C3
			at 20:18 UT: ~ 45 deg.

2007/03/11 (Sunday)

00:12 UT  ES East	Faint ragged front. It fades throughout C3, close to
			its inner edge.

20:00 UT  E Limb	Slow development (very gradual) of a loop front.

2007/03/12 (Monday)

	00:00 - 11:24 UT	LASCO Data Gap (C2 time).
