Electron 2 MeV Integral Flux Alert issued on April 20
An Electron 2 MeV Integral Flux Alert was issued on April 20, 2026, after flux values exceeded 1,000 pfu. The alert remains in effect from April 19, 19:20 UTC, with a maximum observed flux of 1,297 pfu recorded on April 19.
According to NOAA SWPC, significant charging of satellite systems is possible during these elevated electron flux conditions, resulting in increased risk to satellite operations in geosynchronous orbit.
Recent space weather observations indicate that the greater than 2 MeV electron flux at geosynchronous orbit reached high levels at 19:25 UTC on April 19. No major solar events, such as Earth-directed coronal mass ejections or significant solar flares, have been observed in connection with this activity.
