LASCO Activity Report for
July 15, 2004 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

SATURN is still in the C3 FOV (Western hemisphere) after reappearing from
behind the C3 occultor on 2004/07/10 (Saturday) at ~ 05:42 UT.


2004/07/14 (Wednesday)

03:30 UT  N East	Kind of thick jet-like front followed by a diffuse
			and asymmetric ragged loop front whose northern leg
			matches the apparent PA of the jet. They quickly fade.
	
05:06 UT  N East	Initially bright front develops as a ragged faint
			structure with faint extensions to S. It fades in C2.
			
06:30 UT  W Limb	Apparently twisted elongated structure, preceded by a
			kind of spray to N. It fades throughout C3. Couple
			of veru faint and diffuse fronts follow at ~08:30 and
			~11:30 UT.

12:54 UT  N West	Kind of blob-like front.

	14:30 - 15:52 UT	LASCO Data Gap (due to ICAL01: 
				Intercalibration for EIT with CDS).

18:54 UT  W Limb	Faint spray.

21:30 UT  WS West	Faint, diffuse and elongated loop front. It fades in C3.

2004/07/15 (Thursday)

00:30 UT  W Limb	Faint and very narrow expanding loop front, followed
			at 04:54 UT by a slightly brighter spray developing
			slightly toward WSW.

02:30 UT  S East	Initially bright and narrow front along streamer 
			accompanied by a faint and diffuse loop front to S. 
			Very faint extensions also above the E Limb. The event
			fades quickly in C2 and is barely visible in C3 
			(toward SW). GOES recorded and X1.8 X-ray flare from 
			NOAA AR 0649 (S09E51) between 01:30 - 01:48 UT with 
			peak emission at 01:41 UT.

11:30 UT  S West	Diffuse jet front just starting.
