 DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-25T06:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-25T06:36:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the W in SOHO LASCO C2 starting at 2025-06-25T06:36Z. Also seen to the W in SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1. There is some minor northward deflection into the FOV of SOHO LASCO C3. This CME will likely combine with the earlier, slower CME: 2025-05-24T23:48Z. The source of this CME is most likely from beyond the W limb. There is some minor field line movement visible over the W limb in SDO AIA 193 starting around 2025-05-25T06:00Z

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.
