Detection of VHE Gamma-rays above 100GeV from the BL Lac object 1ES1218+304 — •Markus Meyer¹, Thomas Bretz¹, Daniela Dorner¹, Daniel Kranich², Pratik Majumdar³, and Daniel Mazin³ — ¹Universität Würzburg, D-97974 Würzburg, Germany — ²ETH Hönggerberg, CH-8093 Zürich, Switzerland — ³Max-Plank-Institut für Physik, D-80805, München, Germany

The high frequency peaked BL Lac object 1ES1218+304 at a redshift of z=0.182 was observed in January 2005, using the MAGIC Imaging Air Cherenkov telescope. Gamma-rays above ~100GeV are detected. The spectrum can be well described by a steep power law.
