Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-11T05:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-02-11T05:48:00-CME-001 (version 1)
Note Keyword:
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Slow CME seen to the SE in SOHO LASCO C2/C3 and STEREO A COR2. Source is slowly opening field lines seen well beyond the SE limb in SDO AIA 171 and GOES SUVI 284 around 2024-02-11T04:00Z. There is a faint feature preceding but traveling at the same rate as a more defined hollow core.

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 |

Measurement of a core-like feature using a farsided longitude as indicated by UV imagery of the Earth-facing disk. Data gap in SOHO LASCO from 2024-02-11T12:54Z to 2024-02-11T17:39Z and in STEREO A COR2 from 2024-02-11T13:23Z to 2024-02-11T15:23Z. |

Plane-of-sky measurement (which produced a very good fit despite the source location in UV imagery indicating a farsided source) of the faint leading edge which is visible as a distinct loop in early frames of C2 and STEREO A COR2, but becomes diffuse after one frame of C3. |
