Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-05-08T02:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-05-08T02:48:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the NE in SOHO LASCO C2 starting at 2026-05-08T02:48Z. It is also seen to the NE in SOHO LASCO C3 and to the N in STEREO A COR2 but is covered by a data gap in GOES CCOR-1. The source of this CME is most likely an eruption near the NE limb best seen in SDO AIA 304 as a small amount of ejecta leaving the disk starting around 2026-05-08T01:50Z. This CME is overtaken by the following, faster CME: 2026-05-08T04:49Z.
