DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-27T19:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
Activity ID: 2026-06-27T19:23:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
O: Other
Note: Faint CME observed to the SW in STEREO A COR2 and very faintly to the SE in SOHO LASCO C2, following and overlapping with CMEs 2026-06-27T18:53Z and 2026-06-27T19:12Z. No distinct source for this CME is observed, likely farsided, and could be associated with an active region located around E140-E160 (previously located ~E150-E160 at 2026-06-26T07:09Z in Solar Orbiter PHI).

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 |

Triangulation between STEREO A COR2 and SOHO LASCO C2, tracking a very faint leading edge. this leading edge is in close proximity to the leading edges of CMEs 2026-06-27T18:53Z and 2026-06-27T19:12Z, but did not track to them; as such this is likely a separate event amidst those two also on the farside. |
