DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-06T02:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-02-06T02:48:00-CME-001 (version 2)
Note Keyword:
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: CME seen to the SE fully in SOHO LASCO C2/C3, and to the S/SW potentially as a partial halo in STEREO COR2A after 2025-02-06T05:09Z, with the CME front already at the edge of its FOV when its beacon data downlink resumes. Due to this data gap timing in STEREO COR2A, the CME is observed in white light imagery but unresolvable in running difference imagery. Observed as a rapid snapping open and dimming of field lines over the SE limb centered ~S28, best observed in SDO AIA 171/193 around 2025-02-06T02:31Z and GOES SUVI 284 around 2025-02-06T02:34Z. Also observed in SDO AIA 304/GOES SUVI 304 as some filament ejecta. The far-sided nature of this CME is also corroborated via fitting in swpc_cat and the lack of an on-disk signature accompanying the field line movement.

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

CME Analysis M2M_CATALOG SH true SWPC_CAT -150.0 -15.0 1633.0 O 43.0 2025-02-06T04:43Z SHOCK measurement using only SOHO LASCO C2/C3 imagery, as STEREO COR2A beacon running difference imagery does not resolve this front after it resumes from a data gap at 2025-02-06T05:09Z, making triangulation within swpc_cat not possible with real-time imagery. Via visual fitting of this wide shock front, a range of E140-E155 is likely, as further longitudes in either direction make for a poor visual fit of the shock. 1: Result 1 (2.0 AU)
