Pisgah Astronomical Research Institute (PARI [pronounced Perry]) is a non-profit institution located inside Pisgah National Forest in North Carolina dedicated to providing education and research access to several radio as well as optical telescopes to students and researchers alike. The facility was owned by the United States Department of Defense as a satellite tracking station under the name of the Rosman Tracking Station, but it was later torn down and sold to PARI. Three of the radio telescopes, 26-West, 26-East, and Smiley, are left over from the DoD days. The rest of the telescopes were put up by PARI staff.
