Magnetic azimuth

Definitions

  • Webster's Revised Unabridged Dictionary
    • Magnetic azimuth an arc of the horizon, intercepted between the vertical circle passing through any object and the magnetic meridian. This is found by observing the object with an azimuth compass.

Cascades initiated by EHE photons in the magnetic field of the Earth and the Sun
In order to have an idea about the efficiency of cascading, we compute the values of the perpendicular component of the magnetic field along different directions of motions of primary photons, defined by the azimuth and zenith angles (see Fig. 5).

The perpendicular component of the magnetic field reaches the lowest values for direction towards the Equator (the azimuth angle φ = 180o) and the zenith angles corresponding to the values of the angles between the location of the specific observatory and the magnetic pole (Z = αSAO mag or Z = αNAO mag ).
