\section{Introduction} The MAGIC telescope has been designed especially light with a special focus on being able to react fastly to GRB alerts from the satellites. In \cite{design} and~\cite{PETRY}, the objective was set to turn the telescope to the burst position in 10-30~s in order to have a fair chance of detecting a burst with the MAGIC telescope. The current possible value is 20 sec. for full turn-around %FIXME {\it \bf THIS HAS TO BE CHECKED FROM THOMAS B. !!} \par Several attempts have been made in the past to observe GRBs at energies from the GeV range upwards each indicating some excess over background but without stringent evidence. The only secured detection was performed by EGRET which detected seven GRBs emitting high energy photons in the 100~MeV to 18~GeV range~\cite{EGRET}. There have been results suggesting gamma rays beyond the GeV range from the TIBET array~\cite{TIBET} and from HEGRA-AIROBICC~\cite{HEGRA}. Evidence for TeV emission of one burst was claimed by the MILAGRITO experiment~\cite{MILAGRO}. Recently, the GRAND array has reported some excess of observed muons during seven BATSE bursts~\cite{GRAND}. In this context, note especially a recent publication from the TASC detector on \eg~\cite{TASC}, finding a high-energy spectral component presumably due to ultra-relativistic acceleration of hadrons and producing a spectral index of $-1$ with no cut-off up to the detector limit (200 MeV). \par The nowadays most widely accepted model for gamma emission from GRB suggests a bursts environment involving collisions of an ultra-relativistic e$^+$-e$^-$ plasma fireball~\cite{PAZCYNSKI,GOODMAN,SARI}. These fireballs may produce low-energy gamma rays either by ``internal'' collisions of multiple shocks~\cite{XU,REES} or by ``external'' collisions of a single shock with the ambient circum burst medium (CBM)~\cite{MESZAROS94}. \par In many publications, the possibility that more energetic gamma-rays come along with the (low-energy) gamma-ray burst, have been explored. Proton-synchrotron emission~\cite{TOTANI} have been suggested as well as photo-pion production~\cite{WAXMAN,BAHCALL,BOETTCHER} and inverse-Comption scattering in the burst environment~\cite{MESZAROS93,CHIANG,PILLA,ZHANG}. Long-term high-energy gamma emission from accelerated protons in forward-shock has been predicted in~\cite{LI}. Even considering pure electron-synchrotron radiation predicts measurable GeV emission for a significant fraction of GRBs~\cite{ZHANG}. Implications of the observation of a high-energy gamma-ray component on distance scale, energy production in the GRB and distinction between internal and external shock models have been treated in~\cite{HARTMANN,MANNHEIM,SALOMON,PRIMACK}. \par \ldots {\bf MORE ELABORATE TREATMENT OF HE-EMISSION: WHICH MODELS, WHAT TIME DIFFERENCE TO GRB, TIME DEVELOPMENT, EXPECTED FLUXES, SPECTRA } \ldots \par \ldots {\bf UPDATE CURRENT PAPERS} \ldots \par \par \ldots {\bf MORE DETAILED DESCRIPTION OF GEV-EMISSION MODELS }\ldots \par \par \ldots {\bf SATOKO AND MARKUS GARCZ.}\ldots \par In the year 2005, three satellites will produce GRB alerts: The \he satellite, launched in October 2000, the \ig satellite, launched October 2002 and the \sw satellite, launched in October, 2004 and expected to be fully operational in March, 2005. \par Concerning estimates about the MAGIC observability of GRBs, a very detailed study of GRB spectra obtained from the third and fourth \ba catalogue has been made in~\cite{ICRC,NICOLA}. The spectra were extrapolated to \ma energies with a simple continuation of the observed high-energy power law behaviour and the calculated fluxes compared with \ma sensitivities. Setting conservative cuts on observation times and significances, and assuming an energy threshold of 15~GeV, a GRB detection rate of $0.5--2$ per year was obtained for an assumed observation delay of 15~sec. and the \sw GRB trigger rate ($\sim 100/year$). \subsection{Observing XRFs} {\ldots \it \bf CAN BE MAYBE GO INTO A SEPARATE PROPOSAL \ldots \\} \subsection{Observing SGRs} {\ldots \it \bf CAN BE MAYBE GO INTO A SEPARATE PROPOSAL \ldots \\}
