DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-10T15:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-07-10T15:53:00-CME-001 (version 1)
Source Location: S16W47
Active Region Number: 14485
Note Keyword:
3P: 3-part structure CME
DPL: CME exhibits dimpled front
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
OFL: Outflowing material at the back of the CME
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME observed to the SW in STEREO A COR2, GOES CCOR-1, and SOHO LASCO C2/C3 after a downlink gap backfilled in. The source is AR 14485 and a C6.0 flare (S16W47) peaking at 2026-07-10T14:59Z. Also observed well in SDO AIA 171/193 as field line movement, pockets of dimming in the vicinity (not a central area), and a minor EUV wave.

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 SOHO LASCO C2/C3 and STEREO A COR2, using the width in STEREO A COR2 as it appears much less wide in SOHO's field-of-view. Significant overlap with CME: 2026-07-10T13:26Z in COR2's field-of-view muddles a good view of the leading edge for most frames. |

Triangulation between SOHO LASCO C2/C3 and STEREO A COR2 of a faint shock feature best observed in LASCO C2's field-of-view, noting it does measure slower than the bulk. |
