Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-08-30T01:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-08-30T01:48:00-CME-001 (version 1)
Note Keyword:
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the NE in SOHO LASCO C2 starting at 2026-08-30T01:48Z. The CME is also seen to the NE in GOES CCOR-1 and SOHO LASCO C3 and to the NNE in STEREO A COR2. The source of this CME is most likely associated with a C3.0 flare from beyond the NE limb (~N12) that peaked at 2026-08-30T01:20Z. The flare is best seen in SDO AIA 131. Some ejecta from beyond the NE limb can also be seen in SDO AIA 304.
