CME Observed Time: 2023-09-01T03:24ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/26703/-1
CME Note: Bright, wide, and fast CME seen emanating to the west-northwest in SOHO LASCO C2 and STEREO A COR2 imagery in association with a long-duration M1.2-class solar flare from Active Region 13413 (N09W70) and significant eruptive signature consisting of rising and "snapping" plasma seen best in SDO 304, a fast EUV wave seen off the limb moving to the east, quickly and rapidly opening magnetic field lines off the west-northwestern limb in SDO 193 and SDO 171 as well as a post-eruptive arcade signature.
CME was not detected at Earth.

Rules of the Road: CCMC requests that users notify the CCMC, CME
model/technique developers and submitting forecasters/researchers before
performing event and validation studies with data from the CME Arrival
Time Scoreboard. It is recommended that such studies be performed with
the knowledge and collaboration of developers and submitting
forecasters/researchers.
