Compton–Getting effect
The Compton-Getting effect is a predicted anisotropy in the intensity of cosmic rays arriving at Earth due to the movement of the Earth through space.[1] It is named after Arthur Compton and Ivan A. Getting, who predicted it in 1935.
The Compton-Getting effect predicts that the intensity of cosmic rays should be higher coming from the direction in which Earth is moving.[1][2] The effect only applies to cosmic rays that are unaffected by the Solar wind such as extremely high energy rays. [1] It has been calculated that the speed of the Earth within the galaxy (200 kilometres per second (120 mi/s))[2] would result in a difference between the strongest and weakest cosmic ray intensities of about 0.1%.[3] This small difference is within the capabilities of modern instruments to detect,[3] but as of 2005 the Compton-Getting effect has not been confirmed.[2]
