N.T. Palliyaguru (TTU) report on behalf of a larger GROWTH collaboration:
We observed the field of SSS17a/DLT17ck (e.g., Coulter et al. LVC GCN 21529; Allam et al. LVC GCN 21530;
Yang et al. LVC GCN 21531), the possible counterpart of G298048 (LVC, LVC GCN 21505) in NGC 4993, with
the Karl G. Jansky VLA in its B configuration (program 16A-206; PI: Corsi). The observation lasted about
1.25 hr, starting on 17-Sep-03 23:30:57 UT, and was conducted in C-band (approximate central frequency of
6 GHz). We report the detection of a radio source with S/N of about 5. This source was not seen in previous
epochs down to similar limits (e.g. Corsi et al., LVC GCN 21664
