## Summary:
Multiple CMEs have been detected as follows:
1: C-type CME detected by GOES / SOHO.
Start time of the event: 2026-01-12T01:45Z.
Estimated speed: ~804 km/s.
Estimated opening half-angle: 24 deg.
Direction (lon./lat.): -115/15 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-01-12T01:45:00-CME-001
2: C-type CME detected by GOES / SOHO.
Start time of the event: 2026-01-12T03:00Z.
Estimated speed: ~916 km/s.
Estimated opening half-angle: 24 deg.
Direction (lon./lat.): -115/3 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-01-12T03:00:00-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 CMEs may impact Parker Solar Probe (glancing blow). The combined flank of the CMEs may reach Parker Solar Probe at 2026-01-14T01:00Z (plus minus 7 hours).

## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux is above 1000 pfu starting at 2026-01-12T10:05Z.
The elevated energetic electron flux levels are likely caused by the combined arrival of CME with ID 2026-01-08T05:53:00-CME-001 (see notifications 20260108-AL-001, 20260109-AL-002), CME with ID 2026-01-08T15:48:00-CME-001 (see notification 20260109-AL-003), CME with ID 2026-01-08T17:00:00-CME-001 (see notifications 20260109-AL-001, 20260109-AL-003), and CME with ID 2026-01-08T17:12:00-CME-001 (see notification 20260109-AL-003). The combined arrival of these CMEs was likely detected at L1 by ACE and DSCOVR at 2026-01-10T19:36Z (see notification 20260110-AL-003).
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: 2026-01-12T10:05:00-RBE-001.
## Notes:
The arrival of these CMEs is also associated with geomagnetic storm with ID 2026-01-10T18:00:00-GST-001 (see notifications 20260110-AL-004, 20260110-AL-005).
Simulations indicated that the magnetopause separating magnetospheric and solar wind plasma was close to the geosynchronous orbit starting at 2026-01-11T05:56Z (see notification 20260111-AL-002).

## Summary:
O-type CME detected by GOES / SOHO.
Start time of the event: 2026-01-11T22:45Z.
Estimated speed: ~1353 km/s.
Estimated opening half-angle: 36 deg.
Direction (lon./lat.): -115/-5 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-01-11T22:45:00-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 Parker Solar Probe and Psyche (glancing blow). The leading edge of the CME will reach Parker Solar Probe at 2026-01-13T06:07Z and the flank will reach Psyche at 2026-01-17T08:00Z (plus minus 7 hours).

## Summary:
Strong compression of the magnetosphere detected. Simulations carried out at NASA Community Coordinated Modeling Center indicate that the magnetopause separating magnetospheric and solar wind plasma is close to the geosynchronous orbit starting at 2026-01-11T05:56Z.
The activity is associated with Interplanetary Shock with ID 2026-01-10T19:36:00-IPS-001 (see notification 20260110-AL-003) and the combined arrival of CME with ID 2026-01-08T05:53:00-CME-001 (see notifications 20260108-AL-001, 20260109-AL-002), CME with ID 2026-01-08T15:48:00-CME-001 (see notification 20260109-AL-003), CME with ID 2026-01-08T17:00:00-CME-001 (see notifications 20260109-AL-001, 20260109-AL-003), and CME with ID 2026-01-08T17:12:00-CME-001 (see notification 20260109-AL-003), and Geomagnetic Storm with ID 2026-01-10T18:00:00-GST-001 (see notifications 20260110-AL-004, 20260110-AL-005).

## Summary:
C-type CME detected by SOHO.
Start time of the event: 2026-01-10T20:48Z.
Estimated speed: ~809 km/s.
Estimated opening half-angle: 23 deg.
Direction (lon./lat.): 3/-29 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-01-10T20:48:00-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 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 2026-01-13T08:00Z, Solar Orbiter at 2026-01-13T01:00Z, and STEREO A at 2026-01-14T10:00Z (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 2026-01-13T16:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-5 (below minor to minor).
