	  W Limb	Infalling material all along the day.

00:54 UT  E Limb	Wide ragged loop front just appearing above the E Limb.
			An extremely faint and diffuse loop-like extension can 
			be guessed above the S Pole by the time. By 01:31 UT, 
			a big CME can be seen spanning almost all around the
			eastern limb with very faint extensions on the S Pole 
			and western hemisphere. The event is first seen in C3 
			at 01:42 UT above the E Limb with very faint extensions
			already surrounding the occulting disk. The mean
			plane-of-sky speed of the LE of the CME (based on C3
			data) at PA 87 was ~ 800 km/sec (showing practically 
			no acceleration). Gusty outflow on ESE afterward, 
			all along the day and well into next day.
			GOES reported a X1.7 X-ray flare from NOAA AR 10715
			(N06E34) between 00:01 - 00:39 UT, with peak emission 
			at 00:31 UT. EIT 195 images show a brightening on the
			aforementioned AR starting at 00:12 UT, clear signature
			of the X 1.7 X-ray flare. An intensity disturbance 
			(wave) can be seen afterward with epicenter in the
			aforementioned AR; also a dimming region mainly to W 
			and S of the AR.
			In summary, the event has therefore been determined as 
			an asymmetric 'full' halo event, frontsided.

21:30 UT  W Limb	Diffuse spray-like front (asymmetric loop-like feature
			brighter to S).

	  W Limb	Infalling material all along the day.

07:54 UT  S Pole	Diffuse curved feature developing toward SSW. It fades
			in C3 (very faint).

09:30 UT  E Limb	Very faint and diffuse loop front that fades close to
			the inner edge of C3.

10:34 UT  W Limb	Spray-like front. It fades throughout C3. Expanding
			(and very faint) loop-like feature to N.

12:30 UT  WN West	"Pair formation". Separation point at ~ 4.55 solar 
			radii (at PA ~ 293).

2005/01/03 (Monday)

	  W Limb	Infalling material during the first half of the UT day.
			Some small blobs coming out.

04:54 UT  E Limb	Very diffuse brightening develops that extends up to
			the N Pole in the next couple of images is followed 
			on ESE by an expanding ragged loop front. Structures
			on N are seen to be pushed toward NNW. By 06:54 UT
			another faint loop front follows. GOES reported a C3.8
			X-ray flare from NOAA AR 10715 (N05E07) between 
			04:02 - 04:48 UT with peak emission at 04:22 UT.
