Margutti report\non behalf of a larger collaboration:\n\nWe observed the location of the optical counterpart of LIGO/Virgo\nG298048 (Coulter\net al. LVC GCN 21529; Allam et al. LVC GCN 21530) with the Very Large Array\nat a frequency of 6 GHz (C-band) on September 5.925 UT.  We do not detect\nany significant radio emission (S/N>3) and therefore cannot confirm the\nradio detection reported two days earlier by Corsi et al. (LVC GCN\n21815) for a comparable integration time on source and at the same\nfrequency.  This indicates either rapid fading (not expected for off-axis\njet emission), significant variability (not expected from scintillation\ngiven the small source distance and hence large angular size), or a\nspurious detection in the previously reported observations.   Further\nobservations are underway.",
