## Summary:
Significant interplanetary shock detected by ACE and DSCOVR at L1 at 2026-02-14T19:39Z.
The shock is likely associated with the arrival of a coronal hole high speed stream starting on 2026-02-14. Some magnetospheric compression likely and geomagnetic
storm possible.

## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux remains elevated, recently crossing the threshold of 1000 pfu at 2026-02-13T17:45Z.
The elevated energetic electron flux levels (see notifications 20260207-AL-001, 20260207-AL-002, 20260209-AL-001, 20260211-AL-001) observed since 2026-02-07T13:25Z are caused by the arrival of CME with ID 2026-02-02T00:48:00-CME-001 and the coronal hole high speed stream which arrived on 2026-02-05, reaching maximum sustained speeds of approximately 650 km/s (see notifications 20260202-AL-012, 20260203-AL-001). The solar wind speed at L1 is currently around 420 km/s. The arrival of the CME with ID 2026-02-02T00:48:00-CME-001 was detected at L1 by DSCOVR and ACE at 2026-02-04T14:20Z (see notification 20260204-AL-004).
NASA spacecraft at GEO, MEO and other orbits passing through or in the vicinity of the Earth's outer radiation belt can be impacted.
Activity ID: 2026-02-07T13:25:00-RBE-001.
## Notes:
Simulations indicated that the magnetopause separating magnetospheric and solar wind plasma was close to the geosynchronous orbit starting at 2026-02-05T03:55Z due to the arrival of the CME with ID 2026-02-02T00:48:00-CME-001 (see notification 20260205-AL-001).

## Summary:
C-type CME detected by STEREO A / GOES.
Start time of the event: 2026-02-13T09:38Z.
Estimated speed: ~800 km/s.
Estimated opening half-angle: 28 deg.
Direction (lon./lat.): 16/31 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-02-13T09:38:00-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 OSIRIS-APEX (glancing blow), Solar Orbiter (glancing blow), and STEREO A (glancing blow). The flank of the CME will reach OSIRIS-APEX at 2026-02-16T16:00Z, Solar Orbiter at 2026-02-14T14:00Z, and STEREO A at 2026-02-16T14:00Z (plus minus 7 hours).
The simulation also indicates that the CME may 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 2026-02-15T22:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 4-6 (below minor to moderate).
