Recently, the Galactic Center has been reported to be a source of very high eneryg (VHE) γ-rays by the VERITAS, CANGAROO and HESS experiments. The energy spectra as measured by these experiments show substantial differences. We present MAGIC observations of the Galactic Center, resulting in the detection of a differential γ-ray flux consistent with a steady, hard-slope power law. We briefly describe the observational technique used, the procedure implemented for the data analysis, and discuss the results in the perspective of different models proposed for the acceleration of the VHE γ-rays.
