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
