Well this tallies with my observations. The random onset of solar flares is making more sense.
Big Bear Solar Observatory (BBSO) images reveal small-scale magnetic fields in the inner corona may be linked to the onset of a main flare. Study also includes contributions from NJIT's newly commissioned Extended Owens Valley Solar Array (EOVSA). Two hello-observatories worth keeping an eye on.https://www.sciencedaily.com/releases/2017/03/170328145326.htm
