Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-23T15:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-01-23T15:38:00-CME-001 (version 1)
Source Location: N15E20
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
BR: Brightening
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Narrow CME seen to the NE in GOES CCOR-1 and STEREO A COR2; not yet seen in SOHO LASCO (waiting for the downlink). Its source is likely a relatively minor eruption seen starting after 2026-01-23T14:57Z and centered (N15E20) in SDO AIA 193, with dimming and post eruptive arcades.
