In science:

There are however preferred directions along which the photon is unlikely to interact with the magnetic field of the Earth and the shower develops these strange LPM behaviour that have been carefully studied for the southern Auger observatory .
Summary: ZeV Air Showers. Where do we Stand?
Moreover, very low ντ fluxes could be detected very efficiently by Auger detectors by looking at the interaction in the Earth crust of quasi horizontal ντ inducing a horizontal cascade at the detector (88).
In Search for Extraterrestrial High Energy Neutrinos
We calculate the cascades initiated by photons in the magnetic field of the Sun and discuss the possibility of detection of extraordinary showers in the Earth’s atmosphere produced by the secondary photons from these cascades by the Auger Observatories.
Cascades initiated by EHE photons in the magnetic field of the Earth and the Sun
Note that for the surface magnetic fields typical for the Earth and the Sun and for energies of events which may be detected by the Auger Observatory, the parameters χ can reach values above ten.
Cascades initiated by EHE photons in the magnetic field of the Earth and the Sun
Such simulations in the Earth’s atmosphere will be done also for photons arriving from different directions to both Auger Observatories.
Cascades initiated by EHE photons in the magnetic field of the Earth and the Sun
Figure 6: Average numbers of secondary photons, per ∆log (Eγ ) = 0.1, produced in cascades initiated by primary photons with energies 1020 eV (figure (a) and (b)) and 3 × 1020eV (figures (c) and (d)) in the magnetic field of the Earth for location of the Southern Auger Observatory.
