Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-30T00:36Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

GOES: CCOR-1

Activity ID: 2025-05-30T00:36:00-CME-001 (version 1)
Source Location: N15W65

Note Keyword:

DFL: Likely deflection of the event within the FOV

Faint: Faint event; may affect type assignment

Source Signature Keyword:

PEA: Post eruption arcade

FIL: Filament eruption

BR: Brightening

Morphology Keyword:

Note: CME first seen in the NW by SOHO LASCO C2 beginning at 2025-05-30T00:36Z, as well as by SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1 in later frames. The source of this event is a small eruption seen located at approx. N15W65 exhibiting a Northern deflection. This eruption can be seen vaguely in SDO AIA and GOES SUVI 304, but post eruptive arcades are seen in SDO AIA 94, 193, 211 and STEREO A EUVI 195 and 304, more clearly.
