On Jan 2nd we observed PSN J14102342-4318437 (ATel #8434) with the Australia Telescope Compact Array (ATCA). The observations were conducted simultaneously at 5.5GHz and 9GHz. We detect radio emission consistent with the optical position at a level of 5mJy at both frequencies. We note that there is a nearby source visible in the Sydney University Molonglo Sky Survey (SUMSS, 843MHz) at a flux of 75mJy. The SUMSS source is coincident with the nuclear region of the host galaxy NGC 5483, where as the supernova, and our higher frequency radio detection lie in the outer regions of the galaxy, well separated from the SUMSS source. Further observations are planned. We thank the observatory staff for their support and scheduling the observations. The Australia Telescope is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO.
