Note: CME first seen in the West by SOHO LASCO C2 beginning at 2024-09-12T00:36Z. The source of this CME is likely an M5.0 class flare from AR 3811 (S13W78). This CME is quite faint, and the front dissipates quickly.

Measurement based on approximate source location and best fit in SOHO LASCO C2. Front was too faint to be reliably tracked in SOHO LASCO C3 or STEREO A COR2. |
