Electron 2 MeV integral flux alert issued on April 8, 2026

An Electron 2 MeV Integral Flux Alert was issued on April 8, 2026, at 04:59 UTC. The alert was triggered as electron flux levels exceeded the threshold of 1,000 pfu. This continued alert follows high flux measurements that began on April 3, 2026, at 09:20 UTC, with a recorded maximum 2 MeV flux of 7,359 pfu on the previous day.

Potential impacts from this elevated electron flux include significant charging of satellite systems, which increases the risk to satellite operations. Operators should be aware of the elevated electron environment, as indicated in the alert, which may pose a threat to satellite integrity and mission duration.

According to the latest NOAA SWPC forecast, the greater than 2 MeV electron flux is expected to continue at high levels through April 9, with a predicted reduction to moderate levels on April 10. The electron flux remains elevated, but no significant proton activity or Earth-directed coronal mass ejections have been observed during this period.
