Note: CME seen to the SW in SOHO LASCO C2, STEREO A COR2, and GOES CCOR-1. Source is a large filament eruption seen near the SW limb of the Earth-facing disk, and in the SW quadrant of the STEREO-A-facing disk. The filament can be seen spanning S35W60 to S15W108 and beginning to show movement at 2025-09-30T08:36Z. An associated M2.6 flare peaking at 2025-90-30T09:40Z and a narrow jet of ejecta, both from AR 14227 (S17W58), can be seen in GOES SUVI 304. Liftoff of material and post-eruptive brightening can also be seen in STEREO A EUVI 195/304 imagery.

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 |

Best fit measurement using several frames of STEREO A COR2 and GOES CCOR-1. SOHO LASCO was in a downlink period which began at 2025-09-30T09:48Z such that the CME was only visible for two frames of SOHO LASCO C2 at the time of measurement. |
1: Result 1 (2.0 AU)
Juice = 2025-10-02T01:41Z
STEREO A = 2025-10-02T19:00Z
2: Result 2 (5.5 AU)
Juice = 2025-10-02T01:29Z
