DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-08T21:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-08T21:36:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the NE in SOHO LASCO C2 starting at 2025-06-08T21:36Z. CME is also seen to the NE in SOHO LASCO C3 and GOES CCOR-1. CME is seen to the NNE in STEREO A COR2 for two very faint frames. There is some significant deflection toward the N later into the propagation through the FOV of SOHO LASCO C3. The source of this CME is like an eruption from over the NE limb visible in SDO AIA 304 beginning around 2025-06-08T21:22Z. The eruption is also seen as moving field lines from beyond the NE limb in SDO AIA 171. The CME is overlapped at the back by later CME: 2025-06-08T22:12Z.

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
