Transit of the Sun across Constellations Libra, Virgo and Variation of Secondary Gamma Radiation Flux in the Months of November 2018 and September 2019, Respectively at Udaipur, India

Abstract

Abstract: We reported a significant variation of secondary gamma radiation flux (SGR) in month November 2018 and month September 2019 at Udaipur during transit of Sun across constellations. The data was collected as a function of time using a ground-based NaI (Tl) scintillation detector. We interpret such variation of SGR flux on the basis of combined gravitational pulling along with gravitational lensing effect on background radiation by the Sun, constellations and radiation from constellations.
