## 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 2026-01-23T13:00Z.

The elevated energetic electron flux levels observed since 2026-01-21T09:30Z (see notification 20260121-AL-004) are caused by the arrival of 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). Simulations also 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).

## Summary:

Solar activity reached high levels during this reporting period with 1 X-class flare, 4 M-class flares, 3 O-type CMEs, and 12 C-type CMEs (see details below).

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 missions near Earth:

CME Starting time | Predicted Impact (plus minus 7 hours)
-----------------------------------------------------------------------------
2026-01-18T18:09Z NASA missions near Earth at 2026-01-20T01:22Z, Kp index 8 (severe)
(see notifications 20260118-AL-005, 20260119-AL-001, 20260119-AL-004).

The arrival of this CME was detected at L1 around 2026-01-19T18:55Z.

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

CME Starting time | Predicted Impacts (plus minus 7 hours)
-----------------------------------------------------------------------------
2026-01-15T00:36Z OSIRIS-APEX at 2026-01-18T00:00Z (glancing blow) (see notification 20260115-AL-002).
2026-01-15T02:12Z Mars at 2026-01-19T12:00Z (minor impact), Psyche at 2026-01-20T15:00Z (minor impact), Parker Solar Probe at 2026-01-17T06:00Z (glancing blow) (see notification 20260115-AL-001).
2026-01-15T07:12Z Parker Solar Probe at 2026-01-17T02:00Z (glancing blow) (see notification 20260115-AL-003).
2026-01-17T03:00Z Juice at 2026-01-21T04:00Z (glancing blow), STEREO A at 2026-01-21T04:00Z (glancing blow), Europa Clipper at 2026-01-23T12:00Z (minor impact), Lucy at 2026-01-30T04:00Z (minor impact) (see notification 20260117-AL-001).
2026-01-17T07:00Z Juice at 2026-01-21T18:00Z (glancing blow), STEREO A at 2026-01-21T12:00Z (glancing blow), Europa Clipper at 2026-01-24T12:00Z (minor impact) (see notification 20260118-AL-001).
2026-01-18T08:36Z Juice at 2026-01-22T16:00Z (minor impact) (see notification 20260118-AL-003).
2026-01-18T18:09Z Solar Orbiter at 2026-01-19T17:18Z, OSIRIS-APEX at 2026-01-20T13:00Z (glancing blow), STEREO A at 2026-01-21T04:00Z (glancing blow), Juno at 2026-01-29T09:14Z (see notifications 20260118-AL-005, 20260119-AL-001, 20260119-AL-004).

Geomagnetic activity was at severe levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <=8.67 for the reporting period. The highest value of Kp = 8.67 occurred during the synoptic period of 2026-01-19T21:00Z to 2026-01-20T00:00Z (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 at 2026-01-19T18:55Z (see notification 20260119-AL-005) which was associated with the arrival of O-type CME first seen in STEREO A COR2 at 2026-01-18T18:09Z. Simulations indicated that the magnetopause separating magnetospheric and solar wind plasma was close to geosynchronous orbit starting at 2026-01-19T22:49Z (see notification 20260119-AL-008).

The > 2.0 MeV energetic electron flux in the Earth's outer radiation belt was elevated above the threshold level of 1000 pfu at the beginning of the reporting period due to a threshold crossing from the previous reporting period starting at 2026-01-12T10:05Z (see notifications 20260112-AL-002, 20260114-AL-001, 20260116-AL-001, 20260118-AL-002). This elevation of energetic electron flux levels was likely associated with the combined arrival of the O-type CME first seen in STEREO A COR2 at 2026-01-08T05:53Z, the C-type CME first seen in SOHO LASCO C2 at 2026-01-08T15:48Z, and the O-type CMEs first seen in SOHO LASCO C2 at 2026-01-08T17:00Z and 2026-01-08T17:12Z as detected at L1 by ACE and DSCOVR at 2026-01-10T19:36Z (see notification 20260110-AL-003). The energetic electron flux levels returned to background levels on 2026-01-20.

A solar energetic particle event was detected at SOHO, GOES, and STEREO A during the reporting period. At SOHO, the flux of one or more of the >15.8 MeV protons channels exceeded 10^(-1) pfu/MeV starting at 2026-01-18T22:33Z (see notification 20260118-AL-006). At GOES, the flux of > 10 MeV protons exceeded 10 pfu starting at 2026-01-18T22:55Z (see notifications 20260118-AL-007, 20260119-AL-006). At STEREO A, the flux of the 13-100 MeV protons exceeded 10^(-1) pfu/MeV starting at 2026-01-19T10:58Z (see notifications 20260119-AL-003, 20260120-AL-003). This SEP event was associated with the X1.9 flare peaking at 2026-01-18T18:09Z from Active Region 14341 and the associated O-type CME first seen in STEREO A COR2 at 2026-01-18T18:09Z. An additional enhancement in the integral flux of the GOES > 10 MeV protons and a brief elevation below threshold in the integral flux of the GOES > 100 MeV protons was likely associated with the M1.1 flare peaking at 2026-01-19T11:19Z from Active Region 14345. A further enhancement in the integral flux of the GOES > 10 MeV protons starting at 2026-01-19T18:30Z (see notification 20260119-AL-006) was associated with the interplanetary shock detected at L1 by ACE and DSCOVR at 2026-01-19T18:55Z (see notification 20260119-AL-005) which was associated with the arrival of O-type CME first seen in STEREO A COR2 at 2026-01-18T18:09Z. The integral flux of the > 10 MeV protons at GOES, the flux of one or more of the >15.8 MeV protons channels at SOHO, and the flux of the 13-100 MeV protons detected at STEREO A remained elevated through 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: 2026-01-21T00:00Z
## Outlook Coverage End Date: 2026-01-27T23:59Z

Solar activity is expected to vary between low and moderate levels during the outlook period. There are currently eleven numbered Active Regions on the Earth-facing disk. Active Region 14341 (S11W20) produced an X-class flare and M-class flaring during the reporting period, and Active Regions 14345 (S17W13) and 14349 (S14E50) produced M-class flaring into the beginning of the outlook period. These regions 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. The southern portion of a large coronal hole (as seen in available EUV imagery from SDO/AIA 193), which began to cross the central meridian on 2026-01-16, may reach geoeffective longitudes on or around 2026-01-22. The energetic electron flux levels at GOES exceeded the threshold of 1000 pfu starting at 2026-01-21T09:30Z (see notification 20260121-AL-004) and may continue to be elevated during the outlook period.

## 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 2026-01-21T09:30Z.

The elevated energetic electron flux levels are likely caused by the arrival of 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). Simulations also 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).
