Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-09-09T16:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-09-09T16:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Wide, faint CME visible to the SW in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. The CME is also visible to the SE in STEREO A COR2 imagery, and overlaps in the field of view with CME: 2026-09-09T16:09Z. The potential source is unclear, but may be brightening and field line movement seen in the vicinity of AR 14521 (N09W48) beginning at approx. 2026-09-09T14:30Z as seen in SDO AIA 193.

CME Analysis M2M_CATALOG LE true SWPC_CAT 29.0 1.0 282.0 S 35.0 2026-09-10T04:39Z Measurement based on the best fit between SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery in SWPC_CAT. Preliminary measurements of this CME measured less than 200 km/s. This measurement uses additional coronagraph imagery. 1: Result 1 (2.0 AU)
