LASCO Activity Report for
July 07, 2004 SOHO Science Daily Meeting

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.
An archive of these reports is available.

	  HALO aftermath

04:30 UT  EN East	Kind of 'jet' preceding ragged spray-like front 
			slightly to N in the trailing material of the Halo 
			event reported to start at the end of previous day.

05:30 UT  S West	Diffuse and wide loop front in the trailing material 
			of the Halo event reported to start at the end of
			previous day, developing toward SSW. It is followed at 
			07:31 by a kind of 'jet'.

10:06 UT  N West	Spray-like front.

12:56 UT  W Limb	Bright loop front with apparently twisted inner core 
			and twisted trailing material, developing slightly 
			toward WNW. Gusty outflow follows, well into next day.

14:06 UT  S West	Kind of diffuse and asymmetric structure developing 
			along streamer followed at 17:30 UT by a small and 
			ragged loop front.

20:06 UT  S East	Diffuse bright front develops as an asymmetric 'full'
	  (HALO)	Halo CME by 20:30 UT (C2), the part of the front above
			the NW Limb being fainter than the rest. There is no
			significant X-ray activity reported by the time. 
			Likewise EIT Fe XII images do not show any significant 
			activity on the disk. Between 20:00 and ~21:24 UT EIT
			Fe XII running difference images show signatures of a 
			big CME originated in the far side of the Sun, 
			developing mainly toward SE. Therefore, the event could
			be catalogued as a 'full' Halo CME, backsided.

2004/07/07 (Wednesday)

00:30 UT  N East	In the gusty outflow at NE left after the HALO event,
			a ragged loop front with apparently twisted inner
			structure develops. Faint extensions toward N and S, 
			the latter much fainter. It fades throughout C3.

01:31 UT  S East	Ragged loop front. It fades throughout C3.
