Electron integral flux alert issued on March 31, 2026
An Electron 2 MeV Integral Flux Alert was issued on March 31, 2026, after electron flux levels at geosynchronous orbit exceeded 1,000 pfu. This continued alert follows elevated flux beginning on March 22, 2026, with a peak value of 1,358 pfu reported on March 30, 2026.
According to the official NOAA SWPC alert, satellite systems may experience significant charging, resulting in increased risk to satellite operations. This condition can affect the health and reliability of satellite electronics and systems in orbit when high-energy electrons accumulate.
The heightened flux levels are confirmed by the latest SWPC forecast discussion, which reports that electrons greater than 2 MeV reached high levels in the past 24 hours, with an expected continuation of high to moderate flux through April 2, 2026.
