N. R. Tanvir (U. Leicester), A. J. Levan (U. Warwick) report on behalf of the VINROUGE collaboration.
We observed the region around the location of the proposed optical
counterpart of LIGO/Virgo G298048 (Coulter et al. LVC GCN 21529) using
the VIRCAM camera on the wide-field ESO VISTA telescope.
The source is clearly detected with a provisional magnitude
J(AB)=17.5+/-0.1 at Aug-18 00:10 UT. We note that this is consistent with
colours that are flat in Fnu, as noted by Nicholl et al. (LVC GCN 21541)
from DECam data taken at a similar epoch.
Further analysis is ongoing.
We thank the staff at Paranal for their excellent support of these
