Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-11T04:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-07-11T04:38:00-CME-001 (version 2)
Source Location: N45W35
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
O: Other
Note: Faint CME observed to the NE in STEREO A COR2, and NNW in SOHO LASCO C2, also NNW but heavily pylon obscured in SOHO LASCO C3 and GOES CCOR-1. The source is likely a large, diffuse area of slow dimming and field line movement on the NW disk in SDO AIA 171/193, starting as early as 2026-07-11T20:30Z and centered approximately around N45W35, and may be separable with more weak field line movement to the NW in SDO AIA 171 around 2026-07-11T02:51Z but it is not too distinct. This diffuse, slow source is likely also responsible for the preceeding, overlapping CME: 2026-07-11T04:38Z.

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 |

Triangulation between SOHO LASCO C2/C3 and STEREO A COR2, as the CME is partially blocked by the pylon in LASCO C3 and GOES CCOR-1. |
