Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-03T11:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-03T11:48:00-CME-001 (version 1)
Source Location: N14W16
Active Region Number: 14455
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is visible as a partial halo to the north/northwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery, and to the northeast in STEREO A COR2 imagery. The source is an X1.0 flare and subsequent eruption from Active Region 14455 (N14W16) starting around 2026-06-03T11:20Z as seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 195/304 imagery. The associated ejecta displays a southeast deflection as seen in SDO AIA 304 imagery. A faint EUV wave is observed moving northwest of the eruption site, however, in SDO AIA 193 imagery.

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 |

Approximate analysis of the faint partial halo shock front of this CME based on the fit with GOES CCOR-1 coronagraph, in which this front is seen clearer. LASCO imagery is also used. The front is not seen/clear in STEREO A COR2 coronagraph. |
