X1.7 Solar Flare/S2 Radiation Storm

[MP36]

A major X1.7 Solar Flare at 18:37 UTC. An R3 Level Radio Blackout resulted which led to the fading of HF signals on the sunlit side of Earth. Signals have since recovered. The proton levels are on the rise again and the Moderate S2 level Radiation Storm threshold has been reached.
