Electron 2 MeV Integral Flux Alert issued on October 14

An Electron 2 MeV Integral Flux Alert was issued on October 14, 2025, after flux levels exceeded 1,000 pfu. This ongoing alert indicates that elevated electron flux conditions have been present since October 1, 2025, with a maximum flux of 4,078 pfu recorded on October 13, 2025.

Potential impacts include significant charging of satellite systems, resulting in increased risk to satellite operations. These conditions fall under NOAA SWPC standards for alerting when electron flux exceeds threshold values and may require increased vigilance by satellite operators.

According to the latest discussion from NOAA’s Space Weather Prediction Center, the greater than 2 MeV electron flux is expected to remain high on October 14 before returning to normal to moderate levels on October 15 and 16. The current conditions are primarily driven by ongoing space weather activity, including recent active regions and associated flare events.
