LASCO Activity Report for
June 19, 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. Reason presently unknown.
Note that the data processing for C3 exaggerates the effect
of this stray light - the actual counts in the raw images are
higher, but not extraordinarily so
LASCO observations now back to normal cadence since
EIT CCD bakeout ended
