LASCO Activity Report for
August 8, 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 2002/08/12.
Planet Mars is now in C3's field of view, moving L to R
SOHO comets now total 497. Perihelion of SOHO-500 imminent?!
