Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-06T16:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-01-06T16:38:00-CME-001 (version 1)
Source Location: S13E25
Active Region Number: 14334
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
Note: CME visible to the NE in STEREO A COR2, SOHO LASCO C2/C3, and GOES CCOR-1. The source is likely a C4.0 flare starting at 2026-01-06T15:43Z from Active Region 14334 (S13E25) as seen in SDO AIA 131. An eruption with dimming and post-eruptive arcades is best seen in SDO AIA 193. This CME likely exhibits deflection within the field of view. A smaller eruption is seen from Active Region 14336 (approximately S09E57) starting around 2026-01-06T15:07Z, but the larger eruption is believed to be the most likely source candidate.

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 |

Measurement based on the best fit between STEREO A COR2 and SOHO LASCO C2 imagery in SWPC_CAT as well as the potential source location. Only one frame of STEREO A COR2 imagery was available for this measurement, so the fit is approximate. |
