LASCO Activity Report for
March 2, 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.


Points Of Interest

Venus entered the C3 FOV from the right on 2005/02/26 (by the end of
the day).


2005/03/01 (Tuesday)

23:54 UT  S West	Bright loop front develops just behind event reported
(Previous		to start at 22:30 UT on previous day as a three-part
 day)			structure CME - Leading edge, cavity, inner core -
			(ballon-type). Couple of ragged fronts above the W 
			Limb (around 00:54 and 01:54 UT). By 02:54 UT, faint
			and diffuse loop-like extensions can be discerned on 
			S. Association to balloon type CME not clear. Several
			ragged fronts afterward all along the day all across 
			the S Pole. EIT 195 images show no significant activity
			on the disk. However, starting at ~ 22:36 UT (previous
			day), they show signatures of a CME above the SW Limb,
			apparently originated on the backside of the Sun.
 
00:30 UT  NN West	Slow development of a system of expanding loops. New
			front system by 03:30 UT, which at least initially, 
			moves apparently faster than the first one.

13:54 UT  N West	Diffuse and not-well-defined elongated loop front.
			Difficult to give an exact time of first appearance.
			By the time, the slow development of a system of loops
			a little bit to S can be seen superposed in the LOS.
			By ~18:54 UT, a loop front starts to be discerned in 
			the preexistent outflow. It is clearly seen in C3 
			starting at 20:18 UT. The development of the system of
			loops seems to be affected by that of the front at 
			18:54 UT.

20:59 UT  W Limb	Extremely narrow loop-like feature that fades 
			throughout C2.

2005/03/02 (Wednesday)

00:30 UT  S West	Ragged front in the gusty outflow.

01:31 UT  W Limb	Narrow loop-like feature, followed by a similar one
			(though smaller) by 03:30 UT. Another one at 05:30 UT.

Last C2 image analyzed taken at 15:06 UT.
