Start Time: 2026-06-02T17:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-02T17:00:00-CME-001 (version 1)
Note Keyword:
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Bright CME first seen to the Northeast by SOHO LASCO C2 beginning at 2026-06-02T17:00Z. The source of this event is a filament eruption seen along or just beyond the NE limb at approx. N18 as seen in SDO AIA and GOES SUVI 304 beginning at approx. 2026-06-02T16:43Z. Wide opening field lines are also visible in association with this eruption in SDO AIA 171, 193 and GOES SUVI 284.
