Points Of Interest

2004/07/29 (Thursday)

06:54 UT  S West	Bright elongated loop front. GOES recorded a C1.1 X-ray
			flare on NOAA AR 0652 (N05W83) between 06:22 - 06:26 UT
			with peak emission at 06:26 UT.

10:54 UT  WS West	Ragged front later surpassed by next event.

11:54 UT  WS West	Very bright and wide loop front with bright inner core.
			Faint extensions develop on SE and NW (shock?). No 
			X-ray flare reported by that time.  EIT Fe XII shows 
			a filament eruption between 11:12 - 11:48 UT right 
			above the W Limb nearby AR 0652. Material is seen to 
			be pushed toward S. Coming back to C2, starting
			at 16:06, expansion of trailing features and much
			gusty outflow that last until well into next day. GOES
			reported a C2.8 X-ray flare on NOAA AR 0652 (N03W86)
			between 16:28 - 16:38 UT with peak emission at 16:33 UT.
			Mean plane-of-sky speed (based on C3 data) at PA ~250 
			was ~ 1320 km/sec showing practically no acceleration. 
			
14:30 UT  E Limb	Extremely faint (barely visible at the beginning) front
			slowly develops (the core of previous event is already
			out of C2 FOV). By 16:30 UT the front seems to span 
			from the NW limb to the S Pole, though it is difficult 
			to say much due to the trailing material of previous
			event superposed in the line of sight on NW.
		  

2004/07/30(Friday)

00:30 UT  S West	Kind of half loop front (loop seen almost edge on?) in
			the gusty outflow..

08:30 UT  EN East	Faint and narrow expanding loop front.
	
09:30 UT  N Pole	Loop front starts developing.
