Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-29T14:28Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-04-29T14:28:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
J: Jet
Note: Fast jet CME seen to the SW in STEREO A COR2 during a SOHO C2/C3 data gap likely in excess of 1000 km/s. The source at first glimpse and with higher confidence appears to be an eruption just beyond the western limb as seen mostly by quickly darkening field lines off the southwest limb in SDO AIA 171 around 2025-04-29T14:00Z, but with low confidence may be associated with Active Region 4070 (S12W51) as some minor darkening in the active region seen best in GOES SUVI 284 around 2025-04-29T14:00Z. Measurement will be created assuming the limb-related source.

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
