## Summary:
Significant interplanetary shock detected by ACE and DSCOVR at L1 at 2026-05-13T07:22Z.
The shock may be associated with the CME with ID 2026-05-10T13:48:00-CME-001 (see notification 20260510-AL-004) and the arrival of a coronal hole high speed stream. Some magnetospheric compression is expected and a minor geomagnetic storm is possible.
Activity ID: 2026-05-13T07:22:00-IPS-001.
## Notes: This arrival signature is still developing and the cause of this event is under analysis.

## Summary:
C-type CME detected by GOES / SOHO.
Start time of the event: 2026-05-12T15:24Z.
Estimated speed: ~762 km/s.
Estimated opening half-angle: 13 deg.
Direction (lon./lat.): 78/7 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-05-12T15:24:00-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 Juice (glancing blow), Parker Solar Probe (glancing blow), and STEREO A (glancing blow). The flank of the CME will reach Juice at 2026-05-18T06:00Z, Parker Solar Probe at 2026-05-14T03:00Z, and STEREO A at 2026-05-15T16:00Z (plus minus 7 hours).

## Summary:
O-type CME detected by STEREO A / GOES / SOHO.
Start time of the event: 2026-05-10T13:48Z.
Estimated speed: ~1347 km/s.
Estimated opening half-angle: 47 deg.
Direction (lon./lat.): -59/40 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-05-10T13:48:00-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 have a glancing blow at NASA missions near Earth. Simulations indicate that the flank of the CME will reach NASA missions near Earth at about 2026-05-13T14:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 2-4 (below minor).
