Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-09T07:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-09T07:53:00-CME-001 (version 1)
Source Location: S10W34
Active Region Number: 14485
Note Keyword:
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: Possibly two overlapping CMEs visible to the E in STEREO A COR2 imagery and to the S/SW in GOES CCOR-1 imagery starting at 2026-07-09T07:53Z and 2026-07-09T08:23Z based on STEREO A COR2 imagery. The source of this CME(s) is an eruption from the area of Active Region 14485 (S10W34) starting around 2026-07-09T06:56Z to the SW in GOES SUVI 195 with additional eruption signatures to the NW of AR 14485 (S10W34) in GOES SUVI 195 starting around 2026-07-09T07:08Z. There is a following eruption starting around 2026-07-09T07:48Z with associated brightening and dimming to the N/NW of the Active Region spanning roughly from W25 to W10 and S00 to S12. An EUV wave is visible in GOES SUVI 284 following the main eruption with post-eruptive arcades starting around 2026-07-09T08:53Z as seen in GOES SUVI 195 and 284. These eruptions are also visible in STEREO A EUV 195 and 304 as well as in SDO/AIA wavelengths following an eclipse.
