Prediction for CME (2023-03-30T21:12:00-CME-001)

CME Observed Time: 2023-03-30T21:12Z
CME Note: Minor, faint, but wide eruption first seen in SOHO LASCO C2 at 2023-03-30T21:12Z in the southwest, visible in both the SOHO and STEREO A coronagraphs. The source appears to be associated with a minor eruption from AR3262 located near S19W40 and dimming seen best in SDO 193, though the CME's leading edge quickly disappears before exiting the field of view, and the CME itself is too diffuse to reliably pair images between SOHO and STEREO A well. As such, there is significant uncertainty in the width and velocity parameters associated with the measurements.
CME was not detected at Earth.

CCMC 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.
