## Summary:
C-type CME detected by GOES / SOHO.
Start time of the event: 2026-04-24T19:30Z.
Estimated speed: ~575 km/s.
Estimated opening half-angle: 35 deg.
Direction (lon./lat.): 78/37 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-04-24T19:30:00-CME-001
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 CME may impact STEREO A (minor impact), Juice (glancing blow), and Parker Solar Probe (glancing blow). The flank of the CME will reach STEREO A at 2026-04-27T12:00Z, Juice at 2026-04-29T04:00Z, and Parker Solar Probe at 2026-04-26T12:00Z (plus minus 7 hours).
