LASCO Activity Report for
May 25, 2005 SOHO Science Daily Meeting

Planner: K. Schenk, G. Stenborg

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.

	  ES East	Several small, faint and very diffuse ragged fronts 
			along the streamer since late on previous day. They
			all fade quickly in the C2 FOV. The most relevant ones
			shown below.

05:26 UT  ES East	Diffuse front along stremer that fades throughout C2.

08:50 UT  ES East	Diffuse brightening preceding the slow development of
			a system of faint expanding loops. The development
			continues all along the day. By the beginning of next
			day, the expansion seems to become more pronounced.
			EIT 195 images show a slow event form behind the SE
			Limb between 04:12 - 09:24 UT, with continued outflow
			along streamer lines.

14:06 UT  N West	Very diffuse and ragged faint loop front. It fades
			throughout C2. It is followed at ~ 19:27 UT by a
			another diffuse (though samller) front.

2005/05/25 (Wednesday)

06:50 UT  N Pole	Jet-like front developing toward NNW.

	09:26 - 13:27 UT	Temporary DSN Data Gap.
