Description
The HEGRA IACT stereoscopic system, with an energy threshold of about 0.5 TeV, was used to search for γ-ray emission of several low redshift AGN (z<0.2), mostly BL Lacs. Here we present the results of observations that were made since June 1997 at zenith angles up to 40 deg. No evidence for TeV emission is detected and the corresponding upper limits in Crab units are given
