DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-09T21:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-06-09T21:36:00-CME-001 (version 1)
Source Location: S21W19
Active Region Number: 14461
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
OVR: Event partially overlaps with another CME
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: CME first seen to the SW in SOHO LASCO C2 starting at 2026-06-09T21:36Z. It is also seen to the SW in SOHO LASCO C3 and GOES CCOR-1 but is covered by a real-time data gap in STEREO A COR2. The is most likely an eruption from AR 14461 (S21W19) that appears to be heavily deflected southward likely due its proximity to a coronal hole that was centered around N00W05. The eruption is best seen in SDO AIA 193 as moving field lines and a large area of dimming directed toward the south. The eruption is also accompanied by C2.3 class flare from AR 14461 that peaked at 2026-06-09T19:18Z best seen in SDO AIA 131. In coronagraphs, this CME partially overlaps with far-sided CME: 2026-06-09T21:12Z.
