Points Of Interest

2006/07/03 (Monday)

	00:00 - 11:30 UT	LASCO Data gap.

	  W Limb	Gusty outflow.

16:24 UT  E Limb	Very ragged front. It fades throughout C3.

2006/07/04 (Tuesday)

12:54 UT  ES East	Fan-like front. It fades throughout C3.

21:30 UT  SS West	Bright loop front followed by ragged material 
			expanding toward SW well along into next day. GOES
			recorded a C1.4 X-ray flare on NOAA AR 10898 (S08W12)
			between 19:06 - 21:41 UT with peak emission at 20:29
			UT. EIT 195 images show expanding loops from S of
			AR 10898 between 19:36 - 02:48 (+1) UT.

2006/07/05 (Wednesday)

	  S West	Wide and expanding faint loop fronts continue 
			developing all along the day. Several B-class X-ray
			flares were recorded by GOES during the day on NOAA 
			AR 10898. Moreover, a C1.2 X-ray flare was recorded
			on AR 10898 (S10W22) between 08:42 - 09:13 UT with
			peak emission at 08:58 UT. EIT 195 images show another
			eruption from the SW side of AR 10898 between 08:12 -
			11:48 UT. Loops that formed after eruption on previous
 			day linking the AR with the diffuse field to SW now 
			open and erupt.

00:54 UT  S West	Diffuse brightening precedes the development of a 
			ragged and diffuse expanding loop front, which fades
			throughout C3. GOES recorded a B5.2 X-ray flare on 
			NOAA AR 10898 (S09W33) between 00:01 - 01:11 UT with
 			peak emission at 00:40 UT. EIT 195 images show a
 			brightening to SW of AR 10898 between around 01:48 -
 			03:48 UT (loops reconnect there).

08:54 UT  S West	Bright and very wide loop front with bright inner core.
			The event expands from the NW to the SE (clockwise)
			appearing as at least a Partial Halo Event short 
			after first appearing. A slight increase of cosmic
			rays (solar protons) can be observed in C2 by the time.
			Very faint extensions seem to surround the C2 occulting
			disk by 12:30 UT. Gusty outflow follows. The event 
			is first seen (barely appearing all above the SW limb)
			at 09:18 UT. Close inspection of the C3 sequence shows
			the development of 2 fronts (and the inner core): one
 			[1] a little bit ahead developing toward SW (not as 
			wide and bright as the other), and the other [2], much
 			wider and brighter. The latter seems to fully surround
 			the C3 occulting disk by 16:18 UT. By that time its LE
	 		is almost at the end of the FOV (note that the LE of 
			[1] is by that time already past the outer edge of the
 			C3 FOV). The mean plane-of-sky speed of the LE of the
 			two fronts mentioned is as follows (based on C3 data):
			- [1]: at PA 207: ~ 900k km/sec showing practically 
			no acceleration
			- [2]: at PA 225: ~ 630 km/sec showing a slight
 			acceleration.
			GOES recorded an M2.5 X-ray flare on NOAA AR 10898
			(S09W35) between 08:13 - 08:51 UT with peak emission 
			at 08:36 UT. EIT 195 show a strong brightening on AR
 			10898 starting at 08:12 UT and the eruption of a
 			filament sitting at the core of the AR. Extensive 
			dimming regions to SW and NE of AR (extending till
			late afternoon).
