Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-09T19:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-09T19:00:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Thin CME less than 10 half-width to the NE observed in SOHO LASCO C2/C3, STEREO A COR, and GOES CCOR-1. The source is likely some field line movement observed on/just beyond the NE limb starting around 2025-06-09T18:18Z in SDO AIA 171.

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

CME Analysis M2M_CATALOG LE true SWPC_CAT -78.0 41.0 615.0 C 10.0 2025-06-10T01:02Z Triangulated measurement between SOHO LASCO C2/C3 and STEREO A COR2. This CME is notably less than 10 half width and deflects northward, making it difficult to track with the swpc_cat tool. High confidence in its high northern latitude.
