The Sun and its Planets as detectors for invisible matter
  Gravitational lensing of invisible streaming matter towards the Sun could be the explanation of the puzzling solar flares and the unexplained solar emission in the EUV. Assuming that this invisible matter has some form of interaction with normal matter and that there exist preferred directions in its flow, then one would expect a more pronounced solar activity at certain planetary heliocentric longitudes. This is best demonstrated in the case of the Earth and the two inner planets. We have analyzed the solar flares as well as the EUV emission. We observe statistically significant signals when one or more planets have heliocentric longitudes mainly between 230o and 300o. We also analyzed daily data of the global ionization degree of the Earth atmosphere. We observe a correlation between the total atmospheric electron content and the orbital position of the inner three planets. Remarkably, the strongest correlation is appearing with the phase of the Moon.
