Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-25T07:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-02-25T07:53:00-CME-001 (version 2)
Source Location: N17W05
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
SB: Streamer Blowout following CME
Source Signature Keyword:
FIL: Filament eruption
BR: Brightening
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Slow CME, possibly with streamer blowout and with diffuse front seen best to the NE in STEREO A COR2 and N in SOHO LASCO C2 (followed by multiple fronts). This CME is also seen in several early timestamps of GOES CCOR-1 and SOHO LASCO C3. Its source could be a minor filament eruption faintly seen moving in SDO AIA 304 and also indicated by a faint elongated dimming centered around N17W05 in SDO AIA 193, stretching N-S starting around 2026-02-25T06:00Z.

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 |

Analysis based on the fit in three coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1). If the suggested faint filament eruption is the source of this CME, there is a significant deflection northward. |
