The observations were carried out with the MAGIC telescope in the periods 2005 December-2006 January and 2006 December-2007 January. Here we present results from this source, leading to a VHE γ-ray signal with a statistical significance of 5.7 σ in the 2006/2007 data and a measured differential γ-ray flux consistent with a power law, described as dNγ/(dA dt dE) = (1.0 ± 0.2) × 10-11(E/0.4 TeV)-3.1±0.3 cm-2 s-1 TeV-1. We briefly discuss the observational technique used and the procedure implemented for the data analysis. The results are placed in the context of the multiwavelength emission and the molecular environment found in the region of IC 443.
