Sidereal Anisotropy of 10 exp 11 EV Cosmic Rays and Interplanetary Magnetic Field Directions

摘要

The first two harmonics of sidereal wave in the intensity variations of the Budapest underground telescopes are studied on a year-to-year basis. By comparing the sidereal daily vectors obtained in sectors of opposite IMF directions at a pair of similar telescopes located at conjugate latitudes, one is able to disentangle the solar effects from a galactic anisotropy. Applying this procedure for the Budapest and Hobart measurements, the vector ascribable to galactic anisotropy has an amplitude of approximately 0.02% and phase approximately 5 hr. An attempt is made to draw some conclusion on the undistorted galactic anisotropy by taking into account the heliomagnetospheric deflection. (Atomindex citation 11:506785)
