Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-05T15:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-02-05T15:48:00-CME-001 (version 1)
Source Location: S18W17
Active Region Number: 14362
Note Keyword:
DFL: Likely deflection of the event within the FOV
OFL: Outflowing material at the back of the CME
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 S/SW in SOHO LASCO C2/C3, greatly obscured by the pylon in GOES CCOR-1, and to the SE of STEREO A COR2 for 3 frames before a data gap begins at 2026-02-05T16:08Z. The source is likely associated with an M1.8 flare from AR 14362 (S18W17) which peaked at 2026-02-05T15:13Z, observed in SDO AIA 131. Following this flare, a large but faint southerly deflected EUV wave is observed causing a wide swath of dimming and field line wiggling to the south of this region observed in SDO AIA 171/193 and GOES SUVI 284, centered around S45W10 and spanning approximately E25-W30 and S30-S65. Multiple concentric fronts emerge in LASCO C2 following the intial 2026-02-05T15:48Z front, but these are considered part of the same complex bulk.

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 three available STEREO A COR2 frames before its data gap. Multiple concentric fronts are observed in LASCO C2, treated as one front measuring on the leading most edge and capturing the full width of the brighter material. |

SHOCK front analysis, of the very faint shock feature observed in SOHO LASCO C2/C3 and even more faintly in STEREO A COR2. This feature is trackable enough in running difference imagery to get a triangulation, but difficult to properly discern the width, so this analysis is presented with some speculation but a good 3D fit between coronagraphs. |
