LASCO Activity Report for
October 25, 2002 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

A good time for EIT to switch to 304 Angstrom!

2002/10/24

01:50 UT  S Pole	Faint but fairly well-defined loop front,
			soon overtaken/obscured by

02:26 UT  S Pole	Bright asymmetric loop front, thickest and
			brightest in SW resolves to system of fairly
			wide loop fronts spanning ~90 deg over pole

05:50 UT  S West	Narrow ragged front, quite faint

07:27 UT  S Pole	Narrow bright loop front, possible residual
			(core-like?) material front earlier event(s)

08:26 UT  Partial	Wide bright loop front in SW spans ~150 deg
	  Halo		fromt SE to W limb by 08:50. Fainter 
			extensions to E limb and NW. Backsided.
			Some core-like material in SW from 09:26

10:06 UT  N East	Initially faint front moves along streamer
			in partial blowout with increasing brightness.
			Very strong cavity follows, peculiar 'keyhole'
			morphology in ratio images, especially C3

18:54 UT  N West	Ragged front along faint streamer, fades
			through C2. Slight cavity follows. EIT
			eruptive prominence 

20:50 UT  Partial	Bright ragged loop front in SW is ~160 deg
	  Halo		partial halo CME from SW to NE by 22:06.
			Also very faint extension over W limb into 
			NW. Most probably backsided. Some gusty outflow

2002/10/25

00:26 UT  N East	Sequence of ragged loop fronts and cavities, 
			some gusty outflow follows. Moderately wide

03:26 UT  S West	Sequence of faint loop fronts, brightest
			towards centres. Slight cavities follow

05:26 UT  S East	Narrow front along streamer, bright and 
			well-defined. Followed by

07:27 UT  S East	Bright loop front with cavity and bright
			structured core. EIT eruptive prominence.
			Followed by

09:50 UT  HALO		Bright well-defined loop front in SE is
			full halo CME by 10:06 UT, although 
			emission over N pole is faint. Brightest
			from SW to NE, streamers in SW and NE
			disrupted. Huge EIT eruptive prominence 
			reaching to ~ E45 and with obvious 
			non-radial expansion/propagation
