Electron 2 MeV Integral Flux Alert issued on December 23
An Electron 2 MeV Integral Flux Alert was issued on December 23, 2025, after flux levels exceeded 1,000 pfu. The alert was originally triggered on December 21, 2025 at 14:25 UTC and remains in effect, with the most recent maximum flux measured at 1,882 pfu.
During periods of elevated electron flux, satellite systems may experience significant charging effects. This presents an increased risk to satellite operations, including potential anomalies or failures due to enhanced charging in satellite electronics.
According to the latest SWPC Forecast Discussion issued December 23, 2025, enhanced solar wind conditions, influenced by a positive polarity coronal hole high speed stream, are expected to persist through December 25, 2025. No significant solar flares or Earth-directed coronal mass ejections (CMEs) were observed in recent data. The ongoing high electron flux is anticipated to continue in the coming days.
