This image from 1963, showing the construction of the Culgoora Radioheliograph near Narrabri
was featured on the CSIRO_ATNF twitter account recently.
A circular array of 96 antennas,
the Radioheliograph could make a radio image of the sun every second!
It operated from 1967 to 1984, with the Australia Telescope Compact Array
subsequently built on the same site.
The poles on either side of the Control Building brought in signals
from the 96 antennas
on open-wire copper transmission lines.
The Control Building, which has been added on to in the intervening years,
is now the Control Building for the ATCA.
