It confirmed that they're almost nonexistent at sun latitudes north or south of 35 levels, how they symmetrically migrate toward the sun equator, and the way the time of minimal spots is quickly followed by means of the vestiges of a brand new cycle that manifests as maverick high-latitude spots either north and south. additionally, Maunder acknowledged that the spots are magnetic and effect terrestrial compass needles in addition to the aurora borealis. He confirmed specifically how whilst strangely huge spots succeed in the precise heart of the sunlight plus days’ extra of shuttle, terrestrial disturbances and auroral monitors get away far and wide Earth.
