Points Of Interest

2005/10/21 (Friday)

07:48 UT  S Pole	Very narrow loop front (jet-like) developing toward SSW.

08:13 UT  E Limb	Initially bright loop front, barely visible in C3.

12:23 UT  N East	Jet-like front.

14:57 UT  WN West	Ragged front starts to be discernible at around 3.5
			solar radii. It fades throughout C3. Gusty outflow
			all above the western limb since earlier in the day.

17:38 UT  WN West	Another ragged (loop-like) front. It fades throughout 
			C3.

07:31 UT  WS West	Initially bright loop front above the WSW Limb. Couple 
			of hours later, diffuse extensions can be seen to N and
			S, the C2 occulting disk being completely surrounded by
			10:56 UT. The LE of the loop-like feature previously
			described (on WSW) is by that time almost at the end of
			the C2 FOV, while the halo signature on W is barely 
			above the limb. By 09:06 UT, a system of expanding loops
			follows. The event (i.e., the first loop front) is first 
			seen in C3 at 09:42 UT on WSW. A very ragged full halo
			signature can be clearly seen in C3 by 17:18 UT. The 
			mean plane-of-sky speed of the LE of the event at PA 
			246 was about 290 km/sec (based on C3 data). The
			corresponding HT diagram shows a clear acceleration
			profile in the C3 FOV. GOES recorded very low X-ray
			activity all along the day (A-class). Likewise, no
			significant frontsided activity is revealed in EIT 195
			images. The event has therefore been determined as a
			faint Full Halo Event, backsided.

07:31 UT  E Limb	Kind of 'reconnection event' at PA 98 (around 3.85 solar
			radii): asymmetric loop-like front going out, and 
			corresponding infalling feature.

12:54 UT  S West	Elongated and ragged narrow loop front in the trailing
			material (at roughly the southern leg) of the system of
			loops reported to start at 09:06 UT (see event at 
			07:31 UT).

20:58 UT  NN West	Small and elongated loop-like front.

2005/10/23 (Sunday)

	  E Limb	Several 'reconnection-type' events all along the day.
			Gusty outflow and infalling material.

08:06 UT  SS West	Diffuse and ragged loop front that fades throughout C2.

12:30 UT  SS West	Very faint and diffuse front develops as an elongated
			loop-like front. It fades throughout C3. 

18:06 UT  N Pole	Ragged (not-well-defined) front.

2005/10/24 (Monday)

02:54 UT  N West	Loop front with structured interior. EIT 195 images
			show a filament eruption on NW between 01:13 - 05:12 UT.

04:06 UT  N West	A faster (and fainter) front, rather elongated, develops
			superposed in the LOS with previous event. By 05:54 UT
			another faint loop-like front can be discerned a little
			bit to N and ahead of event reported to start at 
			02:54 UT. 

10:30 UT  W Limb	Diffuse front that seems to disturb the development
			of evemt reported to start at 02:54 UT.

Last C2 image available by the time of writing: 13:31 UT.
