Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-08-31T12:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3

Activity ID: 2025-08-31T12:48:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
PRM: Prominence material (filamentary structures)
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: CME first seen to the S in SOHO LASCO C2 starting around 2025-08-31T12:48Z. The CME is also seen to the S in GOES CCOR-1 and STEREO A COR2. It is very faintly visible for a couple of unmeasurable frames in SOHO LASCO C3. The source of this CME is most likely some field line movement from near the S limb best seen in SDO AIA 193, SDO AIA 171, and GOES SUVI 284 beginning around 2025-08-31T10:00Z, possibly related to a small prominence lifting off. Some associated dimming can also be seen in SDO AIA 193. There is also an unlikely possibility that the source is related to eruptive activity from AR 14197. There appears to be some southern and western deflection. This is consistent with the presence of a positive polarity coronal hole in the SE.

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 |
