DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-08T08:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-06-08T08:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
OS: Other and Shock Candidate
Note: CME observed to the SW in STEREO A COR2 and SSW in SOHO LASCO C2/C3 and GOES CCOR-1. The source is very likely far-sided from Earth due to triangulation, likely visible in STEREO A EUVI 195/304 at 2026-06-08T07:25Z as field line dimming and movement on or near its SW limb, which is located around W150 with STEREO A at W60.3.

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 |

Bulk triangulation between SOHO LASCO C2/C3 and two available frames of STEREO A COR2. Front appears slightly more wide in COR2A than C2/C3. |

Shock front triangulation between SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. With the poor image quality in STEREO A COR2 due to a campaign, W162 is used as the bulk longitude source and varying the parameters from there. Tracking the width via CCOR-1's view of the SE/S/SW expanding faint shock front, but the width could vary due to the uncertainty. |
