LASCO Activity Report for
January 23, 2008 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

LASCO will be supporting the Equatorial Coronal Holes Campaign
(Jan 10 - Jan 13, and Jan 17 - Jan 22). The observing sequence
consists of high cadence (5 minutes) C2 orange Filter images at 
100 sec exposure for 6 hours periods (14:55 - 20:55 UT) between a 
pair of Pb sets. FOV: half-field (512x1024) over the West. No C3 
images during that time.

				days (see also Points of Interest above)
				
23:30 UT  S East	Bright and wide expanding loop front (a diffuse 
			brightening can already be seen starting at 
			21:30 UT). Twisted inner structure. C3 shows
			a relatively narrow loop front (first seen at 
			00:42 UT) toward SE followed by the big and wider 
			loop front behind (first seen at 02:18 UT). WIDTH 
			of the wider loop front in C3 at 05:42 UT (the next 
			day): ~ 90 deg. The narrow loop front fades throughout 
			C3.
