TITLE: GCN CIRCULAR NUMBER: 34364 SUBJECT: transient SPT-SVJ025406.5-702837: ATCA follow-up observations DATE: 23/08/08 02:44:48 GMT FROM: Dougal Dobie at Swinburne University of Technology A. Gulati (U. Sydney), D. Dobie (Swinburne/OzGrav), A.Y.Q Ho (Cornell), D.L. Kaplan (UW Milwaukee), T. Murphy (U. Sydney) We observed the location of SPT-SVJ025406.5-702837 (GCN #34301) for 8.5 hours starting from 2023-08-04T22:00 with the Australia Telescope Compact Array (ATCA). Observations were conducted with the C/X receiver with 2x2048 MHz bands centered on 5.5 and 9 GHz. We find marginal (3 sigma) evidence for a source located at RA: 02:54:04.74 Dec: -70:28:37.2, offset from the coordinates of SPT-SVJ025406.5-702837 by ~9 arcseconds, but within the reported 12 arcseconds uncertainty. The source has a flux density of 42+/-12 uJy at 9 GHz but is not detected at 5.5 GHz with a 3-sigma upper limit of ~40 uJy, implying a spectral index of alpha >~ 0.1. We acknowledge the Gomeroi people as the traditional owners of the Observatory site. The Australia Telescope Compact Array is part of the Australia Telescope National Facility (https://ror.org/05qajvd42) which is funded by the Australian Government for operation as a National Facility managed by CSIRO.
