Points Of Interest

2004/01/30

00:06 UT  S West	Bright loop front with cavity and core preceded by 
			a very faint asymmetric ragged front. The LE of the
			loop front has a mean plane-of-sky speed of about 
			~450 km/sec (based on C3 data, at PA ~ 248). For more
			accuracy, the HT plot shows slight acceleration 
			(speed of ~350 km/s close to the inner edge, 
			~ 500 km/sec at  ~ 22 solar radii). Filament eruption
			observed on the SW quadrant of EIT/Fe XII images 
			starting at ~ 22:36 UT on previous day.
 
04:30 UT  S West	Another bright loop front with cavity and twisted core
			at PA coincident with that of southern leg of previous
			event. Prominence eruption seen in EIT Fe XII above SW
			limb starting ~ 02:12 UT.

06:06 UT  E Limb	Fairly faint loop front. It fades throughout C2.

11:54 UT  S West	Small and fast ragged front behind prominence at 
			04:30 UT. At 13:54 UT the feature shows a clear 
			inverted 'boomerang-like' shape. It fades throughout 
			C3. Gusty outflow well into next days.

12:54 UT  N East	Faint narrow ragged front.

13:31 UT  N West 	Faint jet-like front. It fades throughout C2.

18:30 UT  N East  	Very slow 'helmet-like' loops' system develops along
			streamer. Infalling material to N.  

20:30 UT  E Limb	Very faint loop front. It fades close to the inner
			edge of C3 fov.

2004/01/31

09:30 UT  N West	Faint ragged front. It fades throughout C2.

10:34 UT  S East	Faint ragged front followed by twisted material.

18:06 UT  E Limb	Jet-like front developing toward S, slightly bent to N.
			Asymmetric faint ragged loop front develops in parallel
			to S, at PA of event at 10:34 UT, most likely part 
			of that event.

2004/02/01

07:31 UT  W Limb	Spray-like front. It fades throughout C2.

08:30 UT  E Limb	Faint loop front develops. Infalling material is seen
			at the time close to the inner edge of C2. A similar 
			front (fainter) develops above NE limb. They both fade
			throughout C3.

16:06 UT  N East	Spray-like front. It fades close to the inner edge of 
			C3.

19:31 UT  W Limb	Ragged front developing slightly to N. It fades close 
			to the inner edge of C3.

20:30 UT  S East	Fan-like front. It fades throughout C2. It is followed
			at 23:06 UT by a faint asymmetric loop front much
			brighter to N that also fades throughout C2.

22:30 UT  N East	Extremely faint loop front. Difficult to determine time
			of first appearance.

2004/02/02

01:54 UT  S East	Infalling material starting close to the outer edge of
			C2 (PA ~111).

04:30 UT  N East	Bright loop front with strong cavity and trailing
			material, at PA of that of the southern loop's leg of
			event at 22:30 on previous day. At 08:06 material is
			seen to fall down starting at ~2.80 solar radii, and
			at 09:54 a ragged front develops.
