Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-30T07:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-12-30T07:23:00-CME-001 (version 3)
Source Location: N25E38
Active Region Number: 14324
Note Keyword:
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:
FLR: Flare
PEA: Post eruption arcade
Morphology Keyword:
OS: Other and Shock Candidate
Note: Faint CME seen to the NE in all three coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1), with the faint front quickly becoming fuzzy/partially dissipating. The CME is somewhat overlapping with the more southern CME: 2025-12-30T07:00Z. A possible source is a narrow prominence/ejecta rotating northwardly seen starting at 2025-12-30T06:49Z in GOES SUVI 304 (and SDO AIA 304) on/behind the E limb (lat -15), however the fit between coronagraphs shows a much lower longitude, indicating AR 14324 (N25W33) as a possible source. There is a C3.5-class flare in this Active Region at the time.

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 |

Analysis based on the fit with three coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1) and including the northern portion of this fuzzy, dimpled front. Takes into account later timeframes of coronagraphs. Possible source is the C class flare from Active Region 14324. |
