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

Campaign runs to 2002/08/02 (possibly later, TBD)
Planet Jupiter is now in C3's field of view, moving L to R
