Electron 2 MeV Integral Flux Alert issued on March 24

An Electron 2 MeV Integral Flux Alert was issued on March 24, 2026, after electron flux levels at geosynchronous orbit exceeded the 1,000 pfu threshold. The alert has been ongoing since March 22, 2026, at 14:30 UTC, with a recorded peak of 8,285 pfu on March 23 at 19:00 UTC. This alert indicates a period of high energetic electron activity in near-Earth space.

Potential impacts from these elevated electron levels include significant charging of satellite systems, which increases the risk to satellite operations. According to the NOAA Space Weather Prediction Center, such conditions can adversely affect satellite electronics and increase the risk of anomalies or service interruptions.

The continued high electron flux follows recent solar wind and geomagnetic disturbances, with diminishing CME effects and persistent high-speed solar wind streams reported. No major solar flares or additional Earth-directed coronal mass ejections (CMEs) were noted in the latest forecast discussion. Electron fluxes are expected to remain at high levels through March 26 due to these post-storming conditions.
