The strength of the tidal planetary forcing on the Sun proposed by Scafetta (2012) was at its maximum. Numerous major solar flare eruptions occurred when one or more tide-producing planets (Mercury, Venus, Earth, and Jupiter) were either nearly above the event positions or at the opposing side of the Sun (Hung, 2007).
