N2 - We observed the field of SSS17a (Coulter et al., GCN 21529; Allam et al., GCN 21530; Yang et al., GCN 21531), the potential counterpart of the LIGO/Virgo event G298048 (GCN 21509), with the 0.5m Virgin Island Robotic Telescope (VIRT) on August the 19th, starting at 23:19 UT. We performed a series of exposures in the R and Clear filters, with an elevation decreasing from 40 degrees. The weather conditions were good, with a mean seeing of 2-3 arcsec. We detect an excess at the position of the potential counterpart in C filter at 23:54 UT. Strong contamination from the nearby galaxy prevents a precise brightness estimate without galaxy substraction. Further analysis is in progress. The VIRT is still in its commissioning phase. This message can be cited.
