Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-26T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-26T21:12:00-CME-001 (version 1)
Source Location: S30E05
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: CME first seen to the S in SOHO LASCO C2 starting around 2026-06-26T21:12Z. It is also seen to the S in SOHO LASCO C3 and GOES CCOR-1 and to the SE in STEREO A COR2. The most likely source candidate for this CME is a region of southward directed dimming best seen in SDO AIA 195 starting around 2026-06-26T17:34Z centered around S30E05. There is also some field line movement likely associated with this dimming over the S limb best seen in SDO AIA 171 beginning around 2026-06-26T20:06Z and in GOES SUVI 284 beginning around 2026-06-26T19:49Z. A much less likely source candidate for this CME is associated with a C2.4 class flare from AR 14475 (S09W04) that peaked at 2026-06-26T20:21Z. The flare is best seen in SDO AIA 131, but the eruption followed by some post eruptive arcades is best seen in SDO AIA 304 and SDO AIA 195.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |
