Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-03-06T11:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-03-06T11:12:00-CME-001 (version 1)
Source Location: S12W72
Note Keyword:
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
FF: Event fails/disappears before exiting COR2
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
DFLR: Double ribbon flare
FIL: Filament eruption
Morphology Keyword:
F: Flux Rope
Note: Filament eruption seen to the SW in all coronagraphs, but barely in SOHO LASCO C3 and later STEREO COR2A frames as it fizzles fast. Source is likely a filament spanning S04W73 <-> S19W71 at 2024-03-06T10:00Z when it rapidly unfurled moreso than it outwardly erupted, best seen in SDO AIA 304. The front of this CME is quite dimpled and "heart" shaped, fading fast in coronagraph imagery as well.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Analysis only using SOHO LASCO C2/C3 imagery, with only the closest few C3 frames available for use as the front fizzles fast. I found difficulty trying to triangulate this front between SOHO LASCO C2/C3 and STEREO COR2A at all possible longitude ranges--so this measurement assumes a source longitude of W70 in line with the likely source filament. Includes both "bumps" of the front in one cone, using the sides to capture the entire front. |
