Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-12T14:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2025-10-12T14:53:00-CME-001 (version 1)
Source Location: N22W10
Active Region Number: 14246
Note Keyword:
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
BR: Brightening
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: CME seen to the NE in STEREO A COR2 only and likely not seen in SOHO LASCO and GOES CCOR-1 coronagraphs, possibly since it overlaps with a couple of preceding CMEs. Its source could be the C9.6 flare in AR 4246 (N22W10) and an associated eruption with dimming to the SE of this Active Region best seen in STEREO A EUV 195, but also seen in GOES SUVI 131, 171, 195, 284, 304 imagery. The CME partially overlaps with the more northern, 2025-10-12T14:23Z CME which may be associated with the dimming to the NW of this Active Region.

Very uncertain one-coronagraph (STEREO A COR2) analysis of this CME based on the flare in AR 4246 as the (rather speculative) source of this CME. Because the front is not detectable in SOHO LASCO and GOES CCOR-1 imagery and the CME overlaps with two other CMEs, and due to the fact that the flare is accompanied by a very complex-shape dimming this analysis is very approximate. |
