Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-03-19T03:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-03-19T03:12:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: CME seen to the S in SOHO LASCO C2/C3 and STEREO A COR2. Limited SOHO imagery was available for this CME in real time, due to scheduled SOHO maneuvers. Source is ejection of material seen from just beyond the SW limb. Liftoff of material and widely slowly opening field lines are seen starting around 2024-03-19T01:30Z in SDO AIA 171, with later around 02:30Z a more visible loop of material seen departing the corona. The material is heavily deflected to the south/southeast. Other signatures include liftoff of prominence material seen in SDO AIA 304, opening field lines and loop of material seen in SDO AIA 193. Also seen in STEREO A EUVI 304/195 imagery after a data gap as ejecta off the SW limb and opened field lines at 2024-03-19T03:15Z/03:05Z, respectively.

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 |

Measured using best fit between coronagraphs. It is observed that source is beyond but near the S/SW limb with very heavy deflection to the South/Southeast observed in EUV imagery. |
