Points Of Interest

2005/01/21 (Friday)

	LASCO Data still strongly degraded by proton event, though gradually
	subsiding. Some small and/or faint events maybe missing.

04:58 UT  WN West	Bright and elongated loop front. EIT 195 observes a
			compact brightening to NE of the AR 10720, eruption 
			of a compact loop, and opening of larger, off-limb
			structures between 04:31 - 05:26 UT. GOES reported a
			C6.3 X-ray flare from NOAA AR 10720 (N19W69) between
			04:17 - 04:34 UT with peak emission at 04:27 UT. 
			Couple of C1-class X-ray flares more peaking at 
			06:36 and  06:46 UT on AR 10720.

07:23 UT  S East	Elongated and very narrow diffuse loop-like structure
			that fades close to the inner edge of C3.

10:58 UT  WN West	Another bright and elongated loop front (narrower than
			the previous one). Gusty outflow. GOES reported an 
			M1.7 X-ray flare from NOAA AR 10720 (N19W81) between
			10:10 - 10:19 UT with peak emission at 10:16 UT.

15:18 UT  W Limb	Ragged front that quickly fades developing slightly
			toward WSW precedes another (bigger) ragged front at
			17:30 UT. It fades throughout C3 (Very faint). Also
			very faint in C3, fading by 08:18 UT when LE at S Pole
			is at ~ 10.5 solar radii.

23:30 UT  WN West	In the gusty outflow a very faint and not-well-defined
			front can be discerned (difficult to give an exact
			time of first appearance). It fades throughout C3.

2005/01/22 (Saturday)

01:31 UT  E Limb	Jet-like front that quickly fades.

03:54 UT  NN East	Ragged front along streamer that fades in C3.

03:54 UT  WS West	Not-well-defined front that quickly fades.

16:30 UT  S Pole	Extremely faint and diffuse wide loop front developing
			very slowly. It is very difficulto to give an exact 
			of first appearance. By the end of the day is clearly
			discerned already half way to the end of the C2 FOV.

17:30 UT  WN West	Initially bright loop front that apparently fades 
			throughout C2.

20:30 UT  N West	Diffuse jet-like front (just to N of previous event) 
			that quickly fade.

23:06 UT  WN West	Ragged loop front that fades througout C3. Gusty 
			outflow well into next day.

2005/01/23 (Sunday)

00:30 UT  ES East	Very thin and elongated loop-like structure (jet-like)
			at a position that roughly matches that of the south-
			eastern leg of event reported to start at 16:30 UT on
			previous day.

17:06 UT  SS East	Extremely faint expanding loop front already half way 
			to the end of the C2 FOV starts to be discernible. 
			Some infalling material by the time. It fades 
			throughout C3.

2005/01/24 (Monday)

00:30 UT  W Limb	Small blob-like front.

05:30 UT  ES East	Very faint loop front that quickly fades. By that time,
			and a little bit to S, starts to be visible a faint
			and elongated loop front (and corresponding infalling
			material).

11:30 UT  E Limb	Elongated loop-like structure with a fan-like front.
