The high energy electron flux (greater than 2MeV) is expected to vary between background and moderate levels on 28 April in a benign solar wind environment. The CIR ahead of the next high speed stream (Coronal Hole 78) is then likely to compress the radiation belts and redistribute electrons, leading to a drop in the flux. A possible CME arrival early 30th may then also reduce the electron field further, perhaps with a recovery in counts possible by 01 May.

Electron fluence values are likely to remain below the Active threshold (1e8 integrated pfu) through the period, but with a rising trend toward the end of the period.
