Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-08-16T11:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-08-16T11:12:00-CME-001 (version 3)
Source Location: N17E51
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: CME observed to the NE in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. The source is an eruption from an unnumbered area centered at N17E51, observed as field line movement and brightening in SDO AIA 171/193/304 starting at 2025-08-16T10:30Z.

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 |

Preliminary triangulated measurement between SOHO LASCO C2/C3 and STEREO A COR2, showing eastward deflection from the source, although a SOHO data gap starting at 2025-08-16T12:36Z prevents further analysis until imagery backfills. The CME is notably more diffuse in SOHO versus STEREO running difference imagery. The front appears to be observed in GOES CCOR-1, but does not triangulate well with STEREO A COR2; awaiting full SOHO imagery to see the full picture. |
