The evidence of 11-year solar cycle during the Maunder minimun was found in the butterfly diagram and detected also in geomagnetic activity. Cosmogenic izotopes 10Be and 14C confirm also the cyclocity. Most of the aurorae were produced by proton flares in regions with enhanced magnetic field but without production of sunspots.
