Interferometer, looking from the west
The Green Bank Interferometer (GBI) is operated by the
National Radio Astronomy Observatory
at its Green Bank
site in West Virginia. It includes three radio telescopes of 85-foot
(26m) diameter, designated 85-1, 85-3, and 85-2 from left to right
in the picture at left. (85-1 is also known as the Tatel Telescope.) At present,
85-3 is devoted to continuous monitoring of pulsars; 85-1 and
85-2 form a one-baseline interferometer.
Note: the GBI monitoring program has ceased as of October 6, 2000,
due to lack of funding.
Anyone interested in using the GBI who may be able to provide operating
funds should contact Phil Jewell (email@example.com).
