60. Flares are not always the prime suspect. Coronal Holes are much better...

at transferring energy our way. Allfen Waves are usually blocked by magnetic fields, but in a CH senario, The field is wide open and sends a steady stream of high speed protons, as opposed to a flare which is a burst. Time is still required for the charge to reach the point of electron cascade/charge separation failure. Once the peak charge separation is reached at the point of failure, any little jolt can cause the cascade; like a tidal change, a quake somewhere along the plate local boundaries, even compression changes on the surface.

There are many triggers involved, and I don't claim that the sun is the only factor. But to dismiss it out of hand due to a shakey heliodynamic model is so 16th century.
