SOHO/LASCO HALO CME July 11, 2023 FRONTSIDE
C2 Start Time: 19:24 UT
C3 Start Time: 19:54 UT
Type of CME:
Assymmetric HALO CME — FRONTSIDE
pa1: 000 pa2: 360 Total Width: 360 degrees
Velocity Measurements:
C2: 6 points 698.6 km/sec @ PA 165.47
C3: 12 points 879.0 km/sec @ PA 165.31
Average through both(C2/C3) fields: 877.7 km/sec Acceleration: 5.13 m/sec^2.
COMMENT: LASCO C2/C3 show a bright halo CME in the southern region. The
Cme is associated with a large filament eruption centered around
location S35E05 (AR 3363) starting at approximately 19:15 UT, best seen
on SDO AIA 193 , 304 . The event produces dimming toward the south and
is followed by post-eruptive arcades around 20:42 UT.
STEREO Beacon Data
COR2 A, shows a bright CME pointed southwest-southward .
Due to gaps in data, velocity and position measurements could
not be completed at the
time.
Preliminary UCMEO velocity and position measurements are delivered first.
