LASCO Activity Report for
April 11, 2005 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.

Points Of Interest

- SOHO is in telemetry Submode 5 (since 2005/03/11 @ 15:00 UT).

- EIT 195 CME watch at half-res (512x512).
 
- Venus entered the C3 FOV from the right on 2005/02/26 
  (by the end of the day). Still visible.

2005/04/08 (Friday)

00:06 UT  N East	Faint blob-like front starts to be discernible. By
			~ 02:26 UT another one behind becomes discernible.
			They both fade throughout C3.

06:50 UT  E Limb	Very faint and diffuse front that quickly fades.

09:26 UT  NN West	Jet-like front.

10:50 UT  E Limb	Another small front that quickly fades.

11:50 UT  SS West	Jet-like front.

12:26 UT  WS West	Diffuse front preceding another diffuse front at ~
			13:50 UT, along the streamer. By that time, the slow
			development of a ragged system of faint loops along 
			the streamer starts to be discernible.

14:26 UT  NN West	Jet-like front followed by a very narrow and elongated
			loop front (jet-like) by 15:26 UT.

2005/04/09 (Saturday)

00:06 UT  EN East	Faint and diffuse front that quickly fades.

00:26 UT  NN West	Very faint jet-like front.

02:26 UT  N Pole	An extremely faint and diffuse front most clearly
			visible above the N Pole (and by 3:34 above the W
			limb) develops and in the following frames seem to
			surround completely the C2 occulting disk. Nothing 
			can be discerned in C3.

08:06 UT  W Limb	Wide and ragged loop front.

10:26 UT  E Limb	Spray-like front followed at 15:26 UT by another one 
			(much smaller and developing slightly toward ENE).

12:06 UT  S East	Narrow loop front (fan-like).

13:50 UT  W Limb	Another wide and ragged loop front (though brighter 
			than the one at 08:06 UT and apparently developing
			faster). A faint and ragged expanding loop front 
			starts to develop by 15:06 UT, superposed with the
			northern leg of the wide loop front (on NW).
		
19:50 UT  ES East	Faint and elongated expanding loop front.

2005/04/10 (Sunday)

05:50 UT  ES East	Faint spray-like front preceding a bright loop front
			with apparently twisted interior (first appearance
			by 07:27 UT).

19:27 UT  W Limb	Very faint, narrow and diffuse spray-like front. It 
			fades throughout C2.

21:26 UT  SS West	Very faint and diffuse wide asymmetric loop front
			developing very slowly. Difficult to give an exact 
			time of first appearance. System of faint loops 
			develop early on next day on SW.
