## Summary:

Update on CMEs with IDs 2025-04-13T00:12:00-CME-001, 2025-04-13T08:00:00-CME-001 (see previous notification 20250413-AL-002). The 2025-04-13T08:00:00-CME-001 halo CME was reanalyzed in more detail and two additional fronts were included in the current simulation (see CMEs with IDs 2025-04-13T08:12:00-CME-001, and 2025-04-13T07:48:00-CME-001 below). Based on preliminary analysis by the Moon to Mars Space Weather Analysis Office and heliospheric modeling carried out at NASA Community Coordinated Modeling Center, it is estimated that the CMEs may affect BepiColombo, and STEREO A.  The leading edge of the CMEs will reach BepiColombo at 2025-04-14T16:57Z and STEREO A at 2025-04-16T02:50Z (plus minus 7 hours). 

The simulation also indicates that the CMEs may have an impact at NASA missions near Earth. Simulations indicate that the flank of the CMEs will reach NASA missions near Earth at about 2025-04-15T19:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 4-6 (below minor to moderate).
