Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-24T07:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2025-02-24T07:00:00-CME-001 (version 3)
Source Location: N17W21
Active Region Number: 14000
Note Keyword:
HAL: Halo CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
DIM: Dimming
Morphology Keyword:
Note: CME first seen to the WNW is SOHO LASCO C2. CME is also seen as a partial halo mostly to the NW in STEREO A COR2 but is obscured by the pylon is SOHO LASCO C3. This CME is very difficult to distinguish from the previous CME in white light imagery. The source is most likely associated with an M3.3 flare from AR 14000 (N17W21) that peaked at 2025-02-24T07:02Z. The flare and a region of dimming projected south of the flare are seen across SDO AIA and GOES SUVI wavelengths but are best seen in SDO AIA 193. There also appears to be some western deflection.

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 |

Measurement based on running difference imagery from STEREO A COR2 and on-disk source location. There is significant uncertainty in this measurement due to the lack of measurable LASCO C2/C3 imagery. This CME is very difficult to distinguish from the previous CME is C2 and is obscured by the pylon in C3. |
