Electron 2 MeV Integral Flux Alert issued on April 1, 2026
An Electron 2 MeV Integral Flux Alert was issued on April 1, 2026, by NOAA SWPC after electron flux levels exceeded 1,000 pfu. This alert is a continuation from March 22, 2026, and yesterday’s maximum 2 MeV flux reached 1,413 pfu.
Potential impacts include significant charging of satellite systems, which increases the risk to these systems. Operators of satellite technology should be aware of the heightened risk associated with prolonged elevated electron flux levels.
According to the latest NOAA SWPC forecast discussion, electrons greater than 2 MeV at geosynchronous orbit reached high levels, with a peak flux of 1,380 pfu recorded at 16:00 UTC on March 31. The forecast suggests continued high electron flux through April 2 and a return to moderate to normal levels by April 3.
