Prediction for CME (2023-05-30T17:12:00-CME-001)

CME Observed Time: 2023-05-30T17:12Z
CME Note: Faint, slow, loop-like CME seen to the west-northwest in SOHO C2, C3 and appearing slightly brighter in STEREO A COR2 in the same direction. The source is unclear, and thus simulation results are fairly speculative, but measurements indicate some confidence in an Earth-facing source on the Sun between longitudes 20 and 30 degrees. Possibly associated with brightening and dimming seen on the Earth-facing disk early on 2023-05-30 near N00W40, or with a minor eruption near the vicinity of AR3319 with westward deflection. Arrival signature: increase of magnetic field and rotation of components. From LASSOS discussion: there could be two CME arrivals in this signature - one late on 6/3, then another on 6/4 lasting into 6/6, with the interaction region between the two CMEs around 2023-06-04T19:30Z.

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.
