The quasar 3C 279 is one of the best-studied flat spectrum radio quasars. Itis located at a comparatively large redshift of z=0.536: E>100 GeV observationsof such distant sources were until recently impossible both due to the expectedsteep energy spectrum and the expected attenuation of the gamma-rays by theextragalactic background light. Here we present results on the observation of3C 279 with the MAGIC telescope in early 2006. We report the detection of asignificant very high energy gamma-ray signal in the MAGIC energy range on theobservation night of 2006 February 23.
