LASCO Activity Report for
July 16, 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

Additional stray light in C3 images now removed
during standard image processing.

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

00:30 UT  Partial	Wide bright loop front in NE fills quadrant
	  Halo		and more by 02:30, eventually spanning ~150
			deg. Sequence of bright, well-defined loop
			fronts and cavities, some trailing material
			and gusty outflow. Backsided event

06:30 UT  S West	Slow narrow ragged front along streamer,
			some core-like material

11:30 UT  N East	Faint ragged front, possibly residual to
			partial halo event

12:06 UT  S Pole	Very faint slow loop front

16:06 UT  N West	Moderately slow system of ragged loop
			fronts along streamer, some gusty outflow

20:30 UT  HALO		Bright front in NE is full halo CME by 21:06
			although fainter in the S. Fast, ~1100 km/s,
			some trailing material mainly in NE. X3 X-ray 
			flare AR0030, N14E01
