(West Virginia radio telescope)

The Green Bank 140 Foot Telescope is a 43 meter telescope at the Green Bank Observatory in West Virginia operated by the National Radio Astronomy Observatory, a second telescope at the site, in addition to the Green Bank Telescope (GBT). It was built in the 1960s and used in some early Very-long-baseline Interferometry experiments. In 1999 it was retired, but brought back into service in 2005 with new instruments and has been used for ionospheric research, Pulsar hunting, and as a control station for Spektr-R.
