Note:
This CME is measured using an estimate of the source location based on UV imagery. The eruption of the northern portion of filament stretches from N15-S10 and at E05 on the solar disk. This CME is S-shaped and difficult to track in later frames of difference imagery due to overlapping with other CMEs. Data gap in STEREO A difference imagery from 2023-07-31T21:53Z to 2023-08-01T05:23Z restricts measurement to two frames before leading edge of CME exits the STEREO A COR2 field of view.
