Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-12T09:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-12T09:00:00-CME-001 (version 1)
Source Location: S10W68
Active Region Number: 14485
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
Note: Faint and slow CME first seen to the SW by SOHO LASCO C2 beginning at 2026-07-12T09:00Z, as well as by SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1 in later frames. The source of this event is an M1.1 flare from Active Region 14485 (S10W68) which peaked at 2026-07-12T08:11Z as seen in SDO AIA 131. Field line opening and post eruptive arcades are also seen in association with this flare in SDO AIA 171 and 193. This CME is likely deflected due to the eruption proximity to a prominent coronal hole.

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 |
