The prompt radio burst, from Turtle et al. 1987, Nature 327, 38 , with observations from Molonglo, Fleurs (both within 24 hours of the optical SN announcement) and the Parkes-Tidbinbilla Interferometer (PTI) one day later). This burst decayed away and was undetectable at Molonglo (and all other radio telescopes) after September 1987 ( Ball et al. 2001, ApJ, 549, 599 ).
