collaboration report:
We observed Swift GRB 170330A (D'Avanzo et al. GCN 20944) on March 31,
07:00 UT (8.5 hours since the GRB) with one 1-m LCO unit in Cerro Tololo
with the SDSS i filter. Comparing with the PanSTARRS archive data,
within the XRT error circle we do not find any new/variable source down
to i>20.5 mag (with a total exposure of 10x120s at 8.7 hours mid time)
as calibrated against nearby PanSTARRS sources.
