The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is a new ground-based instrument for observing astrophysical sources of gamma-rays in the energy range from 50 to 250 GeV. The first phase of STACEE, using 32 large heliostat mirrors, was completed in the fall of 1998. We describe the STACEE operations and observations during the 1998–1999 winter observing season. We have detected the Crab Nebula with high significance (∼7σ). This result demonstrates that the STACEE concept is sound and that we can expect to make sensitive measurements of gamma-ray sources at energies below 100 GeV. The full STACEE instrument, with 64 heliostats, will be completed during the year 2000. The first three years of observations with the complete instrument will include a range of sources with an emphasis on Active Galactic Nuclei (AGN) and supernova remnants. © 2000 American Institute of Physics.
