Scientific paper
The HEGRA 5 m^2 air Cherenkov telescope (CT1) was used to search for gamma-ray emission above 1.5 TeV from a series of low redshift AGN (Mkn 421, Mkn 501, MS 0116+319, PKS 2209+236, NGC 315 and W Comae). Here we present results from a total of 383 hours of ON-source observations at zenith angles up to 35$^\circ$ made between February 1996 and April 1997 showing positive detections of Mkn 421 and Mkn 501 and upper limits on the other objects' emission. More recent results from observations of Mkn 421 und Mkn 501 will be added at the conference.
