Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-21T20:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-09-21T20:48:00-CME-001 (version 1)
Source Location: N30W117
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
BR: Brightening
Morphology Keyword:
L: Loop
Note: Faint loop CME seen to the NW in SOHO LASCO (and possibly to the N in STEREO A COR2 in one timestamp before data gap). It is likely completely covered by a data gap in STEREO A and is covered by the pylon in GOES CCOR-1. It is better seen in running difference imagery. Its source is a large loop-like prominence that gradually develops on/behind the NW limb as seen from GOES SUVI starting after 2025-09-21T19Z (in GOES SUVI 304). The filament eruption is also seen close to the NW limb in STEREO A EUVI 304 and 195 around (N30W70, very approximately).

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 |

Speculative analysis with one coronagraph (SOHO LASCO), based on the very approximate source location (as seen in STEREO A EUVI close to the NW limb). |
