 DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-23T15:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-01-23T15:12:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
HAL: Halo CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Partial halo CME seen to the SSE in SOHO LASCO and GOES CCOR-1 coronagraphs and to the SW in STEREO A COR2. Its far-sided source could be indicated by the slowly unfolding prominence eruption seen behind the limb after 2026-01-23T11Z in the SE in SDO AIA 304 and 171 and GOES SUVI 304/284.

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
