Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-08-27T18:00Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
STEREO A: SECCHI/COR2
Activity ID: 2026-08-27T18:00:00-CME-001 (version 3)
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
OVR: Event partially overlaps with another CME
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME observed as a full halo to the NE in GOES CCOR-1, and to the W/NW in STEREO A COR2 with a partial halo shock. Not seen in SOHO LASCO C2/C3 real-time due to a DSN gap. The source is far-sided, and may be former AR 14507 expected to be around N05 and W170-W180 at this time. The eruption is only observed in STEREO A EUVI 195/304 after a data gap ends at 2026-08-27T18:45Z as brightening and post-eruptive arcades over its west limb (limb around W158.3, with STEREO A at W68.3), and in SDO AIA 193 and GOES SUVI 284 as an EUV wave visible over the north and west limbs starting around 2026-08-27T17:00Z.

Triangulation between GOES CCOR-1 and STEREO A COR2. The CME structure is complex, and in COR2 two fronts to the NE are observed, with a brighter core following the more faint, outer leading edge that matches with the brightest outer feature in CCOR-1. As such, this fit encompasses that outermost leading edge in COR2A with CCOR-1's leading edge. |

GOES CCOR-1 only shock analysis, somewhat speculative due to the asymmetric shape and poor visibility. The shock may be visible in STEREO A COR2, but is either too faint or obscured by the bright bulk, and does not track well with the more clear shock front observed in GOES CCOR-1. As such, single spacecraft is used with the same longitude as the LE to approximate, and parameters could vary as a result. |
