[ASA] 70th Anniversary of the first radio astronomy interferometry - Australia Day

[John O'Byrne]

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.
