Abstract (from CDS):

Result. from recent observations with the Whipple Observatory gamma-ray telescope are reported; after the successful detection of Markarian (Mkn) 421 particular emphasis was put on the observation of nearby Bl Lacs. The Bl Lac, Mkn 501, which is similar to Mkn 421 in many ways, was detected for the first time as a gamma-ray source. Extensive coverage of Mkn 421 this season revealed unusual variability; one episode of intensity change in April, 1995 was measured with high statistical significance. Upper limits were found for a number of Bl Lacs with z <0.1.
