Points Of Interest

2004/01/23

06:54 UT  S East	Narrow spray-like front followed by a small ragged 
			front at 09:06 UT and a ragged loop front at 11:06 UT, 
			the latter being faster than the one at 09:06 UT.

13:32 UT  E Limb	Ragged loops' front with southern leg at roughly PA
			of previous event.

16:54 UT  S East	Jet-like front at PA coincident with that of the 
			southern leg of previous event followed by spray-like
			front and gusty outflow. Details missed due to data gap.

	17:30 - 19:31 UT	Data Gap.

22:30 UT  S East	Narrow spray-like front slightly N of previous event.

04:30 UT  N West	Jet-like front. Barely visible in C3.
	
05:30 UT  S West	Ragged loop front developing toward S. It fades close 
			to the inner edge of C3 fov, followed at 07:31 UT to
			SE by a small ragged front that fades throughout C3, 
			and gusty outflow all along the day.

05:54 UT  S East	Very faint relative narrow loop front, precursor of
			another loop front that develops very slowly along the
			day (first seen in C3 at 21:18 UT) and continues 
			development well into next day.

19:54 UT  S Pole	Faint narrow twisted structure.

20:06 UT  W Limb	Spray front developing slightly to N.

2004/01/25

19:54 UT  N West	Spray-like front.

	20:58 - 23:30 UT 	Data Gap.

2004/01/26

	02:06 - 09:54 UT	Temporary Data Gap.

13:54 UT  E Limb	Small ragged front developing slightly to S.

15:30 UT  HALO		Loop front on SE limb immediatly followed by another 
			one slightly to N with faint extensions above NE limb,
			both with cavity. Core material (16:06 UT) at the PA of
			the southern leg of the second loop front. By 17:18 UT 
			C3 shows very faint but clearly discernible extensions
			above W, and to a lesser extent above N, limbs. No
		 	significant activity reported by GOES at the time.
			Likewise no significant activity is seen in EIT Fe XII
			images. The event has therefore been determined as 
			a 'full' halo CME most likely backsided.

07:31 UT  N Pole	Very faint narrow ragged loop front and twisted
			trailing material preceded by a small and faint ragged
			front from which it is difficult to determine the time
			of first appearance in C2 (in C3: 05:42 UT).
