Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-19T21:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-19T21:24:00-CME-001 (version 1)
Source Location: S09W121
Active Region Number: 14482
Note Keyword:
FF: Event fails/disappears before exiting COR2
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME with an irregularly shaped leading edge first seen to the W in SOHO LASCO C2 starting at 2026-07-19T21:24Z. This CME is also seen to the W in STEREO A COR2 but disappears before leaving the FOV of STEREO A COR2. It is very faint and difficult to track in both SOHO LASCO C3 and GOES CCOR-1. The source of this CME is beyond the SW limb. Opening field lines and rising filamentary material can been seen over the SW limb in SDO AIA 171 beginning as early as 2026-07-19T19:30Z. There may be two distinct portions of the ejecta creating two features in coronagraphs; however, the greater leading edge appears to move together, so this has been treated as a single event. The eruption can be seen in STEREO A EUVI 304 from former AR 14482 (S09W121) beginning around 2026-07-19T20:15Z due to the instrument cadence.

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 |

Measurement based on best fit between SOHO LASCO C2 and STEREO A COR2 only. The leading edge is too faint/diffuse to track in SOHO LASCO C3 and GOES CCOR-1. |
