High electron flux alert issued on December 27, 2025
A high electron flux alert was issued on December 27, 2025, after the 2 MeV Integral Flux exceeded 1,000 pfu, according to the NOAA Space Weather Prediction Center. This continued alert follows elevated readings recorded since December 21, 2025, with a peak flux of 8,195 pfu observed on December 26, 2025.
Potential impacts include significant charging of satellite systems, increasing the risk to satellite operations. Operators are advised to monitor for heightened satellite anomalies due to the elevated electron flux environment.
The latest forecast discussion noted that solar activity remained low, and no Earth-directed coronal mass ejections (CMEs) were observed. The increased electron flux is expected to remain at high levels on December 27 and 28, before returning to normal to moderate levels by December 29, 2025.
