Electron 2 MeV flux alert issued on April 6, 2026

An alert for Electron 2 MeV Integral Flux exceeding 1,000 pfu was issued on April 6, 2026, at 04:59 UTC. This continued alert indicates that the threshold has been surpassed since April 3, 2026, at 09:20 UTC. The maximum recorded 2 MeV electron flux yesterday was 5,995 pfu, confirming persistently high levels.

Potential impacts from this elevated electron flux include significant charging of satellite systems, which may result in increased risks to satellite operations. Enhanced electron flux environments can pose hazards to spacecraft electronics and subsystems.

According to the latest forecast discussion from NOAA’s Space Weather Prediction Center, the greater than 2 MeV electron flux reached high levels, with a peak flux of 6,000 pfu recorded on April 5, 2026. These conditions are forecasted to persist through April 8, 2026, as the space environment remains slightly enhanced due to the waning influence of a negative polarity coronal hole high speed stream.
