Prediction for CME (2023-04-29T02:23:00-CME-001)CME Observed Time: 2023-04-29T02:23Z
CME Note: Faint CME with what appears to be multiple fronts seen to the S/SW in STEREO A COR2 imagery and more generally to the South in SOHO LASCO C2 & C3 imagery. There is a fairly wide source region with associated brightening and dimming ranging from -20 to -40 degrees latitude and -10 to +30 degrees longitude starting around 01:30Z. This eruption encompasses AR13288. It is best seen in SDO/AIA 193, 304, and 211 as well as STEREO A EUVI 195.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:
Predicted Arrival Time: 2023-05-02T02:41Z (-12.0h, +9.5h)
Confidence that the CME will arrive: 97.0%
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 5.0
Prediction Method: Ensemble WSA-ENLIL + Cone (NASA M2M)
Prediction Method Note:
Ensemble modeling estimates the spread/uncertainty in CME arrival time predictions using the WSA-ENLIL+Cone model due to uncertainties in CME input parameters. This is achieved by measuring N CME input parameters, then performing an ensemble of N runs of WSA-ENLIL cone model. This gives an ensemble of N CME arrival times and impact estimates.

ENSEMBLE PRODUCT IS STILL IN DEVELOPMENT MODE. PLEASE LET US KNOW IF YOU HAVE ANY SUGGESTIONS FOR MODIFICATIONS. Ensemble modeling update on CME with ID 2023-04-29T02:23:00-CME-001 (see previous notification 20230429-AL-001). Based on analysis by the Moon to Mars Space Weather Analysis Office and heliospheric ensemble modeling carried out at the Community Coordinated Modeling Center, it is estimated that the CME may impact STEREO A. For 40 ensemble members (see notes section), simulations indicate that the leading edge of the CME will reach: - STEREO A between about 2023-05-01T14:22Z and 2023-05-02T11:00Z (average arrival 2023-05-01T23:46Z) for 97% of simulations. Additionally the CME is estimated to reach NASA missions near Earth between about 2023-05-01T17:11Z and 2023-05-02T14:39Z (average arrival 2023-05-02T02:41Z) for 97% of simulations. The ensemble-based forecast indicates that there is a 73% chance for the maximum Kp index to be in the 3-5 range (below minor to minor).

Ensemble CME modeling at M2M is performed by building sets of initial CME parameters and carrying out separate simulations for each set. This approach allows a mapping of initial CME parameter uncertainties into a statistical characterization of CME arrival times and impact at locations of interest. Description of links: For each location, the first link shows the WSA-ENLIL+Cone model animation for the median CME input parameters, the second link shows the probabilistic distribution of predicted arrival times histogram, and the third link shows a stack plot of the WSA-ENLIL+Cone modeled magnetic field, velocity, density, and temperature for all ensemble members. For missions near Earth, a histogram of the probabilistic Kp forecast is also provided.
