Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-19T23:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-09-19T23:12:00-CME-001 (version 2)
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: A very faint fuzzy front only seen in a few timestamps of SOHO LASCO C2 and STEREO A COR2 to the NE in both coronagraphs, with possibly a couple of timestamps in SOHO LASCO C3 and GOES CCOR-1. There are multiple faint fronts before and after this one, so any analysis is very speculative. There is a very faint movement/opening of field lines on/behind the NE limb seen around 2025-09-19T23:30Z in GOES SUVI 284 imagery but the fit between coronagraphs indicated an on-disk longitude.

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 |
