Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-11T16:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-11T16:09:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME observed to the W in STEREO A COR2 and W/SW GOES CCOR-1, not in SOHO LASCO C2/C3 in real-time due to an ongoing outage. The source of the CME is likely former Active Region 14479 or AR 14478, estimated to be located ~N17W165 and ~S05W155 at this time. There are two potential eruptive signatures observed on/around the west limb in STEREO A EUVI: one as wide field line breaking and EUV wave in EUVI 195 to the SW starting around 2026-07-11T15:05Z, and prominence movement and brightening in EUVI 304 to the NW starting around 2026-07-11T15:45Z. Of these, the SW field line movement appears to be a better fit based on timing and CME LE/SH appearance.

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 |
