GCN Circular 21933
S. Goedhart (SKA South Africa) reports on behalf of a larger team: MeerKAT, currently being commissioned, observed the location of SSS17a (Coulter et al. 2017, LVC GCN 21529) in L band between 25-Aug-2017 and 17-Sep-2017. No radio afterglow is detected, with upper limits provided below. We also provide the flux density of the host galaxy NGC4993 for each of three epochs. The observations have an effective (unflagged) bandwidth of 0.22 GHz spanning 1.30-1.66 GHz, with a center frequency of 1.48 GHz. Observations done on 25-27 August were reduced together as one epoch (E1; mid-point 26 Aug/08:43 UT). The second epoch consists of jointly analyzed data collected on 5-6 September (E2; mid-point 6 Sep/03:22 UT). The third epoch refers to observations done on 17 September (E3; start time 07:16 UT). NGC4993 flux densities (1 sigma uncertainties): E1: 0.56+/-0.04 mJy (synthesized beam 14.5"x7.8") E2: 0.58+/-0.05 mJy (synthesized beam 11.8"x6.3") E3: 0.61+/-0.03 mJy (synthesized beam 10.4"x4.8") SSS17a flux density limits (3 sigma): E1: <70 uJy E2: <75 uJy E3: <60 uJy We thank the SKA South Africa team for enabling these observations.
