LASCO Activity Report for
July 22, 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

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 C2's field of view, moving L to R
Planet Mercury is now in C3's field of view, moving R to L

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

2002/07/19

01:31 UT  W Limb	Ragged nebulous front fades and disintegrates
			through C2. Some faint continued outflow

06:06 UT  N West	Very faint loop front

09:30 UT  N East	Moderately bright asymmetric front
			with cavity, possibly residual to
			previous day's halo event

15:48 UT  S East	Thick wide bright loop front with cavity
			and bright structured core, fills quadrant.
			Backsided event

16:30 UT  Partial	Wider faster thick bright loop in SE soon
	  Halo		catches previous event. Eventually spans
			~150 deg with possible very faint emission
			around rest of occulting disk. Cavity and 
			bright structured core follow, streamers in 
			NE and SW disrupted. Backsided event.

2002/07/20

14:06 UT  N East	Small bright blob-like front, slow

20:42 UT  HALO		Fast thick bright loop front in E is full
			halo CME by 22:06, though emission in W
			is very faint. Cavity and bright core
			follow. X3.3 X-ray flare from backsided
			active region over SE limb. Much prolonged 
			gusty outflow from SE to NE between the 
			three large events

2002/07/21

10:34 UT  N East	Largest front in semi-steady sequence of
			moderately bright ragged fronts, possibly 
			residual to earlier event

2002/07/22

09:30 UT  S Pole	Fairly faint loop front with slight cavity
