		| Abstract: | 
		Observational and theoretical results indicate that low-redshift BL Lacertae objects are the most likely extragalactic sources to be detectable at TeV energies. Here we present the results of observations of 7 BL Lacertae objects made between 1993 and 1997. During this period the energy threshold of the 3.8m telescope was around 2TeV. Searches for steady long-term emission have been made, and, inspired by the TeV flares detected from Mkn 421 and Mkn 501, a night-by-night timescale search has also been performed for each source. Detailed Monte Carlo simulations are used to estimate upper limits to both steady and short timescale emission. |
