making sun spots spin faster

15 October 2016

At http://phys.org/print395510984.html … a study in October's Nature Communications (2016) by Chang Liu et al based on images of the sun by HINODE and other telescope arrays. The rotation of sun spots builds up magnetic energy that is released in the form of solar flares., However, they have also observed that flares can cause sun spots to rotate up to ten times faster – which tends to accentuate the magnetic nature of flares. Disturbances created in the solar outer atmosphere can also cause direct and significant perturbations on the surface through magnetic fields, a phenomenon not envisages by any solar eruption model (by astrophysicists).
