LASCO Activity Report for
February 16, 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





2005/02/15 (Tuesday)

	  S East	Some ragged and not-well-defined loop fronts all along
			the day.

04:06 UT  W Limb	Faint ragged front. Infalling material. Difficult to
			give an exact time of first appearance. It fades 
			throughout C3.

05:06 UT  E Limb	Extremely faint jet-like front followed at 07:54 UT by
			a very narrow spray-like front. Both features develop
			slightly toward ENE. By 08:30 UT, a faint ragged front
			can be discerned to S, in the aftermath of the gradual
			event reported on previous day.

10:54 UT  WS West	A small blob-like front start to be discerned already
			half way to the end of the C2 FOV, fading throughout
			C3.

20:30 UT  E Limb	Jet-like front developing slightly toward ENE.

20:30 UT  W Limb	Very faint and diffuse wide loop front extending all 
			the way to SW. By 20:58 UT, a diffuse loop front 
			develops above the S Pole. They both are barely
			visible in C3. GOES reported a C1.1 X-ray flare on
			NOAA AR 10734 (practically at the center of the disk)
			between 19:28 - 20:05 UT with peak emission at 19:48 UT.

2005/02/16 (Wednesday)

04:30 UT  E Limb	Elongated and diffuse faint loop-like structure. It is
			followed at 06:54 and 08:06 UT by a couple of similar
			fronts, all of them developing slightly toward ENE.
			They all fade very close to the inner edge of C3.

06:54 UT  S West	System of faint and diffuse expanding loop fronts.

Time of last C2 image analyzed: 13:31 UT.
