Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-01T02:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-01-01T02:24:00-CME-001 (version 1)
Source Location: S15W77
Active Region Number: 13932
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME with a fuzzy front (multiple fronts) to the SW. A possible considered source could be a significant eruption near AR 3939 (S17W15) starting around 2025-01-01T00:30Z as seen in GOES SUVI 131, 171, 195, 284, 304 imagery. An alternative source is the movement of field lines close to/on the SW limb seen in SUVI 195 after 2025-01-01T01:30Z, possibly from Active Region 3932 (S15W77).

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 based on the fit with two coronagraphs. While in SOHO the fuzzy front can be traced over multiple timestamps, in STEREO A COR2 a super faint front to the SW is seen only in two timestamps. |

Measurement based on the potential source location of S17W15. At the time of the analysis, the source eruption from S15W77 was determined to be the more likely candidate for this CME, and the CME was simulated based on those parameters. |
