• Jelbring: Celestial Commensurabilities

    Commensurabilities are calculated based on published orbital periods of planets and satellites. Examples are given for commensurabilities that are strong or very strong. There are sets of com-mensurabilities that involve 3–4 celestial bodies. Our moon–Earth system is probably a key system forming commensurabilities with all the inner planets. The existence and structure of commensurabilities indicate…

  • Charvatova and Hejeda: Cycles Sun-Earth

    Reconstructions of solar–terrestrial (ST) phenomena, in sufficient quality, several thousands of years backward by means of radiocarbon (14C), 10Be or 18O isotopes have been employed for study of possible responses of the ordered (trefoil) and disordered intervals (types) of the solar inertial motion (SIM) as well as of the 370 yr exceptional segments occurring in…

  • Scafetta and Willson: Planets and Sun

    Herein we adopt a multiscale dynamical spectral analysis technique to compare and study the dynamical evolution of the harmonic components of the overlapping ACRIMSAT/ACRIM3 (Active Cavity Radiometer Irradiance Monitor Satellite/Active Cavity Radiometer Irradiance Monitor 3), SOHO/VIRGO (Solar and Heliopheric Observatory/Variability of solar Irradiance and Gravity Oscillations), and SORCE/TIM (Solar Radiation and Climate Experiment/Total Irradiance Mon-itor)…

  • Solheim: Sunspot Cycle Length and Planets

    The Schwabe frequency band of the sunspot record since 1700 has an average period of 11.06 years and contains four major cycles, with periods of 9.97, 10.66, 11.01 and 11.83 years. Analysis of the O-C residuals of the timing of solar cycle minima reveals that the solar cycle length is modulated by a secular period…

  • Mörner et. al: General Conclusions

    In a collection of research papers devoted to the problem of solar variability and its origin in planetary beat, it is demonstrated that the forcing function originates from gravitational and inertial effects on the Sun from the planets and their satellites. This conclusion is shared by nineteen co-authors. https://scienceofclimatechange.org/wp-content/uploads/Morner-et-al-2013-PRP-General-Conclusions.pdf

  • Scafetta and Mörner: A Giant Solar Flare

    On 7 January, 2014 at 18:32 GMT, the Sun unleashed a massive X1.2-class solar flare, seventimes the size of the Earth (NASA News, 2014b). At the occasion there was a strict triple inferior conjunction of Jupiter, Earth and Venus with respect to the Sun. The strength of the tidal planetary forcing on the Sun proposed…
