The HiRes collaboration has searched for intermediate-scale anisotropy of ultrahigh energy cosmic rays in two ways: first a search for variation with declination of the flux of cosmic rays, and second in their arrival directions. The data of the HiRes-II detector was used in the search.

The geomagnetic field declination (D) and horizontal component (H)were observed visually at the Helsinki magnetic observatory between 1844–1912. About 2.0 million single observations of the magnetic components are available. The observing equipment and observation methods were the same for almost 70 years. The Helsinki data series is thus rather homogeneous and suitable for magnetic field analy...
