## 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 2026-01-28T23:35Z.

The elevated energetic electron flux levels observed since 2026-01-21T09:30Z (see notifications 20260121-AL-004, 20260123-AL-002, 20260125-AL-001 and 20260127-AL-001) are caused by the arrival of the CME with ID 2026-01-18T18:09:00-CME-001 (see notifications 20260118-AL-005, 20260119-AL-001, 20260119-AL-004, and 20260119-AL-005).

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: 2026-01-21T09:30:00-RBE-001.

## Notes:

The arrival of this CME was associated with a severe geomagnetic storm with ID 2026-01-19T18:00:00-GST-001 (see notifications 20260119-AL-007, 20260120-AL-001, 20260120-AL-002, and 20260121-AL-001). Additionally, simulations indicated that the magnetopause separating magnetospheric and solar wind plasma was close to the geosynchronous orbit starting at 2026-01-19T22:49Z (see notification 20260119-AL-008).

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 was estimated that the following CMEs were predicted to impact the listed locations:

2026-01-25T12:00Z OSIRIS-APEX at 2026-01-28T04:00Z (minor impact), Solar Orbiter at 2026-01-27T06:00Z (glancing blow), STEREO A at 2026-01-28T18:00Z (glancing blow) (see notification 20260125-AL-002).
2026-01-25T20:12Z OSIRIS-APEX at 2026-01-28T15:32Z, STEREO A at 2026-01-28T08:14Z (see notification 20260126-AL-001).
2026-01-25T21:48Z OSIRIS-APEX at 2026-01-28T15:32Z, STEREO A at 2026-01-28T08:14Z (see notification 20260126-AL-001).

Geomagnetic activity was at strong levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <= 7.33 for the reporting period. The highest value of Kp = 7.33 occurred during the synoptic period of 2026-01-21T00:00Z to 2026-01-21T03:00Z (see notifications 20260119-AL-007, 20260120-AL-001, 20260120-AL-002, 20260121-AL-001). This enhancement in geomagnetic activity was associated with the interplanetary shock detected at L1 by ACE and DSCOVR during the previous reporting period at 2026-01-19T18:55Z (see notification 20260119-AL-005) which was associated with the arrival of the O-type CME first seen in STEREO A COR2 at 2026-01-18T18:09Z.

The > 2.0 MeV energetic electron flux in the Earth's outer radiation belt crossed the threshold level of 1000 pfu starting at 2026-01-21T09:30Z (see notifications 20260121-AL-004, 20260123-AL-002, 20260125-AL-001, 20260127-AL-001). This elevation of energetic electron flux levels was associated with the arrival of the O-type CME first seen in STEREO A COR2 at 2026-01-18T18:09Z as detected at L1 by ACE and DSCOVR at 2026-01-19T18:55Z (see notification 20260119-AL-005). The energetic electron flux levels remained elevated above background levels through the end of the reporting period.

A solar energetic particle event was detected by STEREO A during the reporting period. The flux of 13-100 MeV protons exceeded 10^(-1) pfu/MeV starting at 2026-01-21T03:00Z (see notifications 20260121-AL-002, 20260121-AL-003, 20260122-AL-001, 20260123-AL-001). This SEP event was associated with the arrival detected by STEREO A IMPACT/PLASTIC at 2026-01-21T03:04Z of the O-type CME first seen in STEREO A COR2 at 2026-01-18T18:09Z which was associated with the X1.9 flare peaking at 2026-01-18T18:09Z from Active Region 14341. The flux of one or more of the >15.8 MeV protons channels detected at SOHO and the energetic integral proton flux of >10 MeV protons detected at GOES remained elevated above their respective thresholds at the beginning of the reporting period due to a threshold crossing starting on 2026-01-18 from the previous reporting period. The energetic proton fluxes at SOHO, GOES, and STEREO A returned to near background levels by the end of the reporting period.

Space Weather Impact:
Space weather impacts on NASA spacecraft are expected to have been high this reporting period due to the solar energetic particle event and elevated energetic electron flux in the Earth’s outer radiation belt described above.

## Space Weather Outlook:
## Outlook Coverage Begin Date: 2026-01-28T00:00Z
## Outlook Coverage End Date: 2026-02-03T23:59Z

Solar activity is expected to vary between low and moderate levels during the outlook period. There are currently ten numbered Active Regions on the Earth-facing disk. Active Region 14349 (S14W45) produced C-class and M-class flaring activity during the reporting period and may continue to produce similar levels of flaring activity during the outlook period.

Geomagnetic activity is expected to vary between low and moderate levels during the outlook period. An equatorial coronal hole (as seen in available EUV imagery from SDO/AIA 193) crossed the central meridian on 2026-01-24 and may reach geoeffective longitudes on or around 2026-01-28. The energetic electron flux levels at GOES exceeded the threshold of 1000 pfu starting at 2026-01-21T09:30Z (see notifications 20260121-AL-004, 20260123-AL-002, 20260125-AL-001, 20260127-AL-001) and may continue to be elevated during the outlook period.
