LASCO Activity Report for
July 24, 2002 SOHO Science Daily Meeting

Planner: K. Schenk, G. Lawrence

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

C2 high-cadence pB sequence campaign now running.
C2 pB sequences being taken every hour at the expense
of 1 normal C2 image and 1 normal C3 image.
Campaign runs to 2002/08/02 (possibly later, TBD)

Planet Jupiter is now in C3's field of view, moving L to R
Planet Mercury is now in C3's field of view, moving R to L
Planet Mars is now in C3's field of view, moving L to R

The presumed source region of last week's backsided halo
CMEs has now traversed the SE limb - presently unnumbered


2002/07/23

00:42 UT  HALO		Fast wide bright front over E limb is full
			halo CME by 01:42, though emission in E is 
			faint and 'shock-like' as opposed to bright
			CME material. Much trailing material in E.
			X4.8 X-ray flare AR0039(?) S12E73

03:30 UT  N West	Bright loop front along streamer with much
			trailing material. Large part of streamer 
			removed

06:30 UT  N West	Narrow ragged loop front, quite bright,
			from same/nearby source region as previous
			event but considerably faster. Some gusty 
			outflow

11:06 UT  S West	Very faint slowly-rising system of loops
			and loop fronts take ~18 hrs to traverse
			C2. Slightly faster brighter core-like 
			material follows early next day

15:06 UT  S East	Faint loop front fades quickly

16:42 UT  N West	Very faint asymmetric loop front

18:42 UT  N West	Wide bright multiple-loop front system
			a little to S of previous event from 
			same region. Slow moving, fills quadrant
			by 22:30. Cavity and looped core

2002/07/24

	10:20 - 14:10 UT	Temporary DSN data gap
