Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-19T16:38Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-09-19T16:38:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
J: Jet
Note: Faint, narrow CME seen to the SW in SOHO LASCO C2 and STEREO A COR2 and very faintly seen in a couple of stamps of GOES CCOR-1 coronagraph, not seen in SOHO LASCO C3. Its source is likely seen in STEREO A EUV 304 imagery as a large ejecta off the W limb after 2026-09-19T15Z and not seen in any other EUV imagery. The ejecta is very fuzzy, it's exact location/longitude is unclear, but it seems to be close to the limb (which would be ~159 deg).

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 |

Approximate analysis based exclusively on the fit of the narrow front in two coronagraphs (SOHO LASCO C2 and STEREO A COR2); longitude of 143 deg seems to be the highest longitude allowing the fit. This analysis is partially confirmed by the possible source - a lifting filament seen in STEREO A EUV 304 close to the west limb as seen from STEREO A (close to 159 degrees). |
