Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.

Points Of Interest

SATURN is still in the C3 FOV (Western hemisphere) after reappearing from
behind the C3 occultor on 2004/07/10 (Saturday) at ~ 05:42 UT.

2004/07/12 (Monday)

05:06 UT  W Limb	Loop front that fades close to the inner edge of C3.
			Faint extensions to N in C2.

08:06 UT  E Limb	Wide and bright loop front with twisted inner core.
			Starting at ~07:36 UT EIT Fe XII show signatures of a
			huge limb event, originated barely behind the disk.	

11:06 UT  S West	Faint and ragged elongated loop front, followed at
			12:30 UT, slightly to N, by another (brighter) ragged
			loop front. Apparently, another one at 17:54 UT, not
			well defined.

22:30 UT  ES East	Very elongated front. 

2004/07/13 (Tuesday)

00:54 UT  N West	Ragged loop front brighter to S and with faint 
			extensions also to S. By 01:31 UT the extensions cover
			the C2 occultor. By 01:31 UT on NNW, bright and slower
			material appears developing toward NNW followed by an
			apparently twisted (rather circular) structure. GOES
			recorded high X-ray activity during the day. In
			particular, NOAA AR 0646 (by the time at N14W45), 
			produced an M6.7 X-ray flare between 00:09 and 00:23 UT
			with peak emission at 00:17 UT, most likely associated
			to the event. EIT Fe XII shows a brightening above the
			aforementioned AR starting at 00:12 UT followed by a 
			wave apparently centered in the AR. Material is seen
			ejected form nearby the AR toward N short after the
			flare.

01:54 UT  N East	Ragged loop front preceded by a fainter and more 
			diffuse front at 01:31 UT. Difficult to characterize 
			the event as it mixes with the faint extensions from
			previous event.

06:06 UT  WS West	Faint ragged fan-like front that fades throughout C3.

09:08 UT  WN West	Another bright ragged loop front with faint extensions 
			to S. By 10:06 UT the faint extensions seem to cover
			the C2 occultor.  GOES recorded an M5.9 X-ray flare 
			on NOAA AR 0646 (by the time at N14W51), between 08:39
			and 09:15 UT with peak emission at 08:48 UT. EIT Fe XII
			shows a brightening above the aforementioned AR starting
			at 08:48 UT followed by an intensity disturbance 
			travelling mainly toward NW.
