C. Guidorzi (U. Ferrara), A. Gomboc (U. Nova Gorica), S. Kobayashi
(LJMU), C.G. Mundell (U. Bath), on behalf of a large collaboration report:
The 2-m Liverpool Telescope automatically began observing INTEGRAL GRB
160401A (Mereghetti et al. GCN 19251) on April 01, 20:23:44 UT, i.e. 3.2
minutes since the GRB trigger time. From the subtraction of two 3x10-s
r-band frames taken at 46 and 68 minutes post GRB trigger we do not
detect any uncatalogued, significantly variable object within the
INTEGRAL error circle down to r~20 mag calibrated against nearby USNOB-1
stars, in agreement with previous reports (Rebolo et al. GCN 19252).
