    Hi RGZooites,
    I was reminded of this cool fact today as Australia celebrates Australia Day. I thought that you all may be interested in this too!
    cheers,

    Today in Australia marks the 70th anniversary of the first radio astronomy interferometry done by radio astronomers in the world.

    A sea cliff interferometer was used by Ruby Payne-Scott at Dover Heights - Sydney at sunrise 26 January 1946. Strong Type I bursts (1 Million Jansky) were observed, arising from a large sunspot. The paper was submitted to the Proceedings of the Royal Society on 22 July 1946 and published 22 August 1947 by the CSIR (pre-CSIRO) Division of Radiophysics team of Lindsay McCready , Joe Pawsey and Ruby Payne-Scott (observations by Payne-Scott). Chris Hales has sent out a message on Twitter today about this anniversary.
