## Summary:
S-type CME detected by STEREO A / GOES.
Start time of the event: 2026-08-14T05:09Z.
Estimated speed: ~496 km/s.
Estimated opening half-angle: 36 deg.
Direction (lon./lat.): 19/14 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-08-14T05:09:00-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 this CME may affect Parker Solar Probe, Europa Clipper (glancing blow), Juice (glancing blow), OSIRIS-APEX (glancing blow), and STEREO A (glancing blow). The leading edge of the CME will reach Parker Solar Probe at 2026-08-15T19:40Z (plus minus 7 hours). The flank of the CME will reach Europa Clipper at 2026-08-17T18:00Z, Juice at 2026-08-17T16:00Z, OSIRIS-APEX at 2026-08-18T00:00Z, and STEREO A at 2026-08-17T20:00Z (plus minus 7 hours).
The simulation also indicates that the CME may have a minor impact at NASA missions near Earth. Simulations indicate that the leading edge of the CME will reach NASA missions near Earth at about 2026-08-17T00:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-5 (below minor to minor).
