    7070We determine the maximum zenith angle for GRB observations by requiring that the overwhelming majority of possible GRBs will have an in principle observable spectrum. Figure~\ref{fig:grh}
    7171shows the gamma-ray horizon (GRH) as computed in~\cite{KNEISKE}. The GRH is defined as the
    72 gamma-ray energy at which a part of $1/e$ of a hypothiszed mono-energetic flux gets absorbed after

    7373travelling a distance of $d$, expressed in redshift $z$ from the earth. One can see that at typical
    74 GRB distances of $z=1$, all gamma-rays above 100\,GeV get absorbed before they reach the earth.
