Lorenzi \n(INAF/TNG), Albar Garcia de Gurtubai Escudero (INAF/TNG), report on \nbehalf of the CIBO collaboration:\n\nWe observed the field of GRB 150222A (Bernardini et al., GCN 17486) with \nthe 3.6m TNG telescope equipped with the DOLoRes camera. Observations \nconsisted of 4 images in the I band for a total of 20 min exposure. The \nseeing was poor (3.2\").\n\nNo object is detected within the (currently unenhanced) XRT position, \ndown to a limiting magnitude I > 22.3 (calibrated against nearby USNO \nstars). The mean time of the observation was 2015 Feb 23.055 UT, that is \n8.4 hr after the GRB.",
