Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-30T16:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-07-30T16:53:00-CME-001 (version 2)
Source Location: N18W65
Active Region Number: 14492
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
DFLR: Double ribbon flare
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME observed as a NE halo in STEREO A COR2, and a NW halo in GOES CCOR-1 partially blocked by the pylon. SOHO LASCO C2/C3 not available in real-time due to a downlink gap, but observed as a NW halo here once imagery backfilled. The source is associated with an M1.9 flare from AR 14492 peaking at 2026-07-30T17:00Z, observed in SDO AIA 131. This eruption is also observed as filament ejecta in SDO AIA 304 first lifting as early as 2026-07-30T15:18Z, more eruptively after 2026-07-15:43Z. SDO AIA 171/193 observe brightening, dimming, field line movement, EUV wave, and post-eruptive arcades.
