Gamma ray emission from the Sun 5 – 150 GeV, 2008 – 2022 (UV overlay)

Plots presenting the solar emission of gamma rays of energies between 5 and 150 GeV per photon. In the plot to the left, the lighter colours (yellow and orange) represent the density of emissions of these high energy photons. It is evident the tendency for this emission to occur on the polar regions, especially during the period of inversion of the signs of the solar magnetic field. This inversion coincides with the peak of the Sun’s activity (June 2014) and is registered in the plot on the right by the crossing of the coloured bands that represent the strength of the magnetic field on the north and south poles. Data collected between August 2008 and January 2022 by the Fermi-LAT space telescope, of NASA. It was superimposed on the left a false color image of the Sun in ultraviolet light, obtained with NASA’s Solar Dynamics Observatory in December 2014.
