Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-05T04:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-05T04:00:00-CME-001 (version 3)
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: A bright symmetrical partial halo seen to the east in both coronagraphs. Its source is a clear, wide opening of field lines behind the east limb seen ~2025-04-05T03:55Z in SDO AIA 171/193 and GOES SUVI 284, later followed by post-eruptive arcades gradually appearing from behind the east limb, as seen in SDO AIA 193/304/131. It overlaps with a slightly later CME that is seen as a more full halo in STEREO A.

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 |

Very approximate analysis of the main brightest front/loop, obtained by fitting with two coronagraphs. Based on the coronal signatures, the source is behind the east limb, but close enough to the limb for the tops of the post-eruptive arcades to start peaking from behind the limb two hours after the eruption. |
