TITLE: GCN CIRCULAR NUMBER: 25676 SUBJECT: GRB 190829A: ATCA cm-band detection DATE: 19/09/06 13:54:36 GMT FROM: Tanmoy Laskar at U of Bath T. Laskar (Bath), S. Bhandari (CSIRO), G. Schroeder, W. Fong, K. D. Alexander (Northwestern), E. Berger (Harvard), R. Chornock (Ohio U.), D. Coppejans, R. Margutti (Northwestern), E. Ayache, C. G. Mundell, P. Schady, and H. J. van Eerten (Bath), report on behalf of a larger collaboration: "We observed GRB 190829A (Fermi GBM team, GCN 25551; Dichiara et al, GCN 25552) with the Australia Telescope Compact Array beginning at 2019 Aug 30 16:10 UT, 20.2 hours after the burst. We detect the cm-band afterglow at the position of the mm-band counterpart (de Ugarte Postigo et al., GCN 25589) with a preliminary flux density of ~ 2 mJy at 5.5 GHz. Further observations are on-going. We thank the CSIRO staff for rapidly scheduling these observations. The Australia Telescope Compact Array is part of the Australia Telescope National Facility which is funded by the Australian Government for operation as a National Facility managed by CSIRO."
