Observations of the BL Lacertae Object 3C 66A with STACEE


We present the analysis and results of recent high-energy gamma-ray observations of the BL Lac object 3C 66A conducted with the Solar Tower Atmospheric Cerenkov Effect Experiment (STACEE). During the 2003-2004 observing season, STACEE extensively observed 3C 66A as part of a multiwavelength campaign on the source. A total of 33.7 hr of data was taken on the source, plus an equivalent-duration background observation. After cleaning the data set a total of 16.3 hr of live time remained, and a net on-source excess of 1134 events was seen against a background of 231,742 events. At a significance of 2.2 σ this excess is insufficient to claim a detection of 3C 66A but is used to establish flux upper limits for the source.
