Full description

In August 2001 an extremely strong isolated burst of radio emission was detected at Parkes. This "Lorimer burst" is now infamous. It apparently originated from a cosmological distance and shows all the characteristics of having traversed this large distance: frequency-dependent dispersion and scattering. Despite this there have been some who have claimed this signal to be merely a terrestrial source of interference, masquerading as something astrophysical. Furthermore, many other such bursts were expected but had not been seen, until now. We have discovered another burst, which occured 2 months earlier, in a search of archival Parkes data. Its implied distance is also cosmological. Our observations will investigate the nature of this second burst and should help unravel the mystery of these phenomena.
