In 1977, the Miami Valley Astronomical Society (MVAS) was fortunate to be able to secure a lease with the State of Ohio (ODNR) for an abandoned Air Force satellite tracking facility in John Bryan State Park. Located just northeast of Yellow Springs, the John Bryan State Park Observatory is about 20 miles from the Apollo Observatory (see above). The facility sports a 15′ dome and is located in a fenced-in compound providing significant security for its equipment. Access is controlled the MVAS.
