LASCO Activity Report for
March 1, 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

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

2005/02/28 (Monday)

00:54 UT  N East	Jet-like front that quickly fades.

06:06 UT  W Limb	Very narrow and elongated loop-like structure.

10:34 UT  N West	Extremely faint, elongated, and diffuse loop-like
			structure. It fades throughout C2.

	17:00 - ~19:40 UT	No LASCO/EIT Observations.

22:30 UT  S Pole	Very bright and wide loop front. Slight excess 
          Complex	intensity above the S Pole can be discerned since
       Partial Halo	22:06 UT. During its development in C2, at least 2
	 		components can be distinguished: i) a wide ragged
			loop front developing mainly toward SW, and ii) a
			ragged loop front developing toward SSE, partly
			superimposed with the other loop front. By 23:54 UT,
			a relatively small loop front can be seen developing
			on SW (see event at 23:54 UT). GOES registered no
			significant X-ray activity during the time. Likewise, 
			EIT 195 images show no significant activity on the 
			disk. However, starting at ~ 22:36 UT, they do show
			signatures of a CME above the SW Limb, apparently
			originated on the backside, most likely the EIT 
			counterpart of event first seen at 23:54 UT.

23:54 UT  S West	Bright loop front develops just behind previous event
			as a three-part structure CME - Leading edge, cavity,
			inner core - (ballon-type). Couple of ragged fronts 
			above the W Limb early on next day (around 00:54 and
			01:54 UT). By 02:54 UT on next day, faint and diffuse
			loop-like extensions can be discerned on S.

2005/03/01 (Tuesday)

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.

	07:31 - 13:31 	Temporary Data Gap.
