Bannister (CSIRO), on behalf of the VAST collaboration.\n\nFollowing the reported VLA detection of a radio source (Mooley et al.;\nLVC GCN 21814, Corsi et al.; LVC GCN 21815) coincident with the optical\ntransient SSS17a (Coulter et al. LVC GCN 21529) we conducted further\nobservations of NGC 4993 with the Australia Telescope Compact Array at\n5.5 and 9 GHz. Observations started at 2017-09-04 22:43:04 UT and ended\nat 2017-09-05 10:03:04 UT with approximately 9.5 hours of on-source time.\n\nWe did not make a robust detection, although there is marginal emission\nat the 4-sigma level, at a position consistent with that reported by\nMooley at al. and Corsi et al. This could be associated with the host\ngalaxy or the optical transient.\n\nAnalysis is ongoing, and subsequent epochs are planned.\n\nThank you to CSIRO staff for supporting these observations.",
