Geomagnetic activity reached minor levels with Kp index (a measure of geomagnetic activity, ranging 0-9) <=4.67 for the reporting period. The highest value of Kp = 4.67 occurred during the synoptic periods of 2025-11-27T09:00Z-12:00Z and 2025-11-27T18:00Z-21:00Z.
The > 2.0 MeV energetic electron flux in the Earth's outer radiation belt was elevated above the threshold level of 1000 pfu due to a threshold crossing from the previous reporting period starting at 2025-11-25T12:50Z (see notifications 20251125-AL-001, 20251125-AL-002, 20251127-AL-001, 20251129-AL-002, 20251201-AL-004). This elevation of energetic electron flux levels was likely associated with the arrival of a coronal hole high speed stream detected at L1 by DSCOVR and ACE on 2025-11-24. The energetic electron flux levels remained elevated through the end of the reporting period.
The energetic proton flux of >10 MeV protons detected at GOES and the 13-100 MeV protons at STEREO A were all at background levels for the entire reporting period.
Space Weather Impact:
Space weather impacts on NASA spacecraft are expected to have been moderate this reporting period due to the elevated energetic electron flux in the Earth's outer radiation belt described above.

## Space Weather Outlook:
## Outlook Coverage Begin Date: 2025-12-03T00:00Z
## Outlook Coverage End Date: 2025-12-09T23:59Z
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 14299 (N22E45) produced significant flaring activity including the X-class flare 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. The energetic electron flux levels at GOES exceeded the threshold of 1000 pfu starting at 2025-11-25T12:50Z (see notifications 20251125-AL-001, 20251125-AL-002, 20251127-AL-001, 20251129-AL-002, 20251201-AL-004, 20251203-AL-002) and may continue to be elevated during the outlook period due to the arrival of a coronal hole high speed stream detected at L1 by DSCOVR and ACE on 2025-11-24 during the previous reporting period. A coronal hole centered around N15W40 (as seen in available imagery from GOES/SUVI 195) may reach geoeffective longitudes beginning on or around 2025-12-03.

## 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 2025-12-03T10:05Z.
The elevated energetic electron flux levels observed since 2025-11-25T12:50Z are caused by a coronal hole high speed stream which arrived on 2025-11-24, reaching a maximum speed of approximately 830 km/s (see notifications 20251125-AL-001, 20251125-AL-002, 20251127-AL-001, 20251129-AL-002, and 20251201-AL-004). The solar wind speed observed at L1 is currently around 400 km/s.
NASA spacecraft at GEO, MEO and other orbits passing through or in the vicinity of the Earth's outer radiation belt can be impacted.
