Abstract

IT has been proposed^1,2 that sunspot activity is affected by positions of the planets, and calculations have been presented³, which purport to show that planetary tides on the Sun vary in the same way as the sunspot variations. We believe that the apparent agreement of the sunspot cycle with planetary tidal effects is an artefact of the calculation.
