LASCO Activity Report for
July 5, 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 starts today.
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)
2002/07/03
00:54 UT S East Faint front, slight cavity
02:54 UT W Limb Sequence of fairly narrow loops,
moderately bright
12:30 UT S East Initially quite bright ragged loop front
fades through C2
15:30 UT S West Fairly large blob
19:31 UT W Limb Thick bright loop front, quite wide, cavity
and core-like region follow. Faint extensions
down to S pole
20:30 UT N West Slowly-rising loops along streamer, much
prolonged outflow follows
20:54 UT S West Bright loop front, quite wide and thick.
Large cavity and small core-like region
follow

05:30 UT S East Faint ragged loop front
05:54 UT S Pole Narrow ragged loop front along streamer
07:31 UT S East Fairly wide bright loop front with cavity
08:06 UT W Limb Fairly wide ragged front along streamer
18:54 UT S East Initially quite bright asymmetric loop
front fades through C2
20:06 UT W Limb Wide bright loop front with cavity, some
trailing material. C5.3 X-ray flare AR0017,

before data gap
04:30 - 11:54 UT Temporary DSN data gap
