Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-03-09T22:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-03-09T22:36:00-CME-001 (version 4)
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
KEY: Keyhole-hole shaped CME
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: A very bright NE partial halo CME with bright H-alpha-like emissions seen in SOHO coronagraph (and even in the AIA imagery). The source is a an eruption seen behind the NE limb in AIA 304/195/171 after 2024-03-09T21Z as a moving field line in AIA 171 and fast restructuring of magnetic field (seemingly far behind the limb) in AIA 193, closely followed by a bright loop-like ejecta from behind the NE limb seen in AIA 304/171/193 imagery, which can be traced to an unusually bright loop-like emission seen in C2/C3 coronagraphs. A very faint (likely more backsided) halo shock is also observed, in addition to the bright front (likely the CME bulk) and the closely following possibly secondary front that can be traced to the loop-like ejecta above.

A very approximate analysis of the brighter bulk of this CME (vs fainter likely more backsided shock). Analysis is based on the fitting of the front with one coronagraph (SOHO) in swpc_cat tool. The uncertainty of the CME longitude is significant because the source is behind the limb based on the lower coronal signatures) and the CME is not seen in STEREO coronagraph because of a large data gap. The longitude can vary from -110 to -150 degrees, so the speed of the CME could be even faster. Helioseismology data from GONG indicate that the former AR 3590 was at ~-177 degrees at the time and so is unlikely to be the source of this CME. |
